The crust and upper mantle make up Earth's ____________
- Lithosphere
- Asthenosphere
- Core
- Continents
Correct Answer

A. Lithosphere

Explanation

The crust and upper mantle make up Earth's lithosphere. The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle. It is divided into several tectonic plates that float on the semi-fluid asthenosphere below. The lithosphere is responsible for the formation of continents, ocean basins, and the movement of tectonic plates.

Plates move apart at ____________ boundaries
- Convergent
- Stable
- Divergent
- Transform
Correct Answer

A. Divergent

Explanation

At divergent boundaries, plates move apart from each other. This movement creates a gap between the plates, which allows magma from the mantle to rise and fill the space. As the magma cools and solidifies, it forms new crust, leading to the formation of new landforms such as mid-ocean ridges and rift valleys. This process is responsible for the creation of new crust and the continuous spreading of the seafloor.

A lack of explanation for continental drift prevented many scientists from accepting that a single supercontinent called _________________ once existed.
- Glomar
- Glossopteris
- Pangaea
- Wegener
Correct Answer

A. Pangaea

Explanation

The lack of explanation for continental drift prevented many scientists from accepting that a single supercontinent called Pangaea once existed. Continental drift is the theory that suggests that the Earth's continents were once joined together in a single landmass and have since drifted apart. Without a proper explanation for this phenomenon, scientists were hesitant to accept the idea of a supercontinent. However, with further evidence and research, the theory of Pangaea has gained widespread acceptance in the scientific community.

Plates slide past one another at ______________.
- Subduction zones
- Transform Boundaries
- Convection Currents
- Divergent Boundaries
Correct Answer

A. Transform Boundaries

Explanation

Transform boundaries occur when two plates slide past each other horizontally. This movement can be in the same direction, causing a shearing motion, or in opposite directions, causing a tearing motion. Transform boundaries are characterized by frequent earthquakes and the absence of volcanic activity. These boundaries are responsible for the formation of faults, such as the San Andreas Fault in California.

Seafloor spreading occurs because ____________.
- New material is being added to the asthenosphere
- Earthquakes break apart the ocean floor
- Sediments accumulate at the area of spreading
- Molten material beneath Earth's crust rises to the surface
Correct Answer

A. Molten material beneath Earth's crust rises to the surface

Explanation

Seafloor spreading occurs because molten material beneath Earth's crust rises to the surface. This process is known as mantle convection, where hot material from the mantle rises and spreads apart at the mid-ocean ridges. As the molten material cools and solidifies, it forms new oceanic crust, pushing the existing crust away from the ridge. This continuous process of molten material rising and solidifying leads to the spreading of the seafloor.

Wegner believed that the continents originally broke apart about ___________ years ago.
- 200 Million
- 300 Million
- 400 Million
- 500 Million
Correct Answer

A. 200 Million

Explanation

Wegner believed that the continents originally broke apart about 200 million years ago. This is based on the theory of continental drift, which suggests that the Earth's continents were once joined together in a single landmass called Pangaea and have since moved apart. Wegner's theory was supported by evidence such as the fit of the continents, matching geological features across continents, and similar fossils found on different continents. This theory revolutionized our understanding of Earth's history and laid the foundation for the development of plate tectonics.

Rate this question:
8.

A fossil plant that helps support the theory of continental drift is ____________.
- Mesosaurus
- Glossopteris
Correct Answer

A. Glossopteris

Explanation

Glossopteris is a fossil plant that supports the theory of continental drift because its remains have been found in several different continents that are now widely separated. This suggests that these continents were once connected and then drifted apart over time. The distribution of Glossopteris fossils provides evidence for the movement of continents and the existence of a supercontinent in the past.

Bands of rock on the seafloor showing alternating magnetic orientation indicate Earth's magnetic field has __________.
- Reversed itself in the past
- Weakened
- Become stronger
- Retained the same
Correct Answer

A. Reversed itself in the past

Explanation

Bands of rock on the seafloor showing alternating magnetic orientation indicate that Earth's magnetic field has reversed itself in the past. This is because when molten rock solidifies and forms new crust on the seafloor, it preserves the orientation of the Earth's magnetic field at that time. By studying these bands of rock, scientists have discovered that Earth's magnetic field has undergone reversals, where the magnetic north and south poles switch places. This phenomenon provides evidence of the dynamic nature of Earth's magnetic field over time.

Rate this question:
10.

A _______ is a sensitive device used to detect magnetic fields on the seafloor.
- Seismometer
- Magnetometer
- Geologist's Compass
Correct Answer

A. Magnetometer

Explanation

A magnetometer is a sensitive device used to detect magnetic fields on the seafloor. It measures the strength and direction of the magnetic field, which can provide valuable information about the geology and structure of the seafloor. By detecting variations in the magnetic field, a magnetometer can help scientists identify and map underwater features such as underwater volcanoes, fault lines, and mineral deposits.

Scientists believe that differences in _____ cause hot, plasticlike rock in the asthenosphere to rise toward Earth's surface.
- Density
- Magnetism
Correct Answer

A. Density

Explanation

The correct answer is density. Scientists believe that differences in density cause hot, plasticlike rock in the asthenosphere to rise toward Earth's surface. Density refers to the mass per unit volume of a substance, and in this case, the denser rock sinks while the less dense rock rises. This movement of the hot, plasticlike rock is known as convection, and it plays a crucial role in plate tectonics and the formation of volcanic activity.

Rate this question:
12.

In order to complete a convection current, the rising material must eventually _________ Earth.
- Stop inside the
- Cool the
- Sink Back Into
- Warm
Correct Answer

A. Sink Back Into

Explanation

In order to complete a convection current, the rising material must eventually sink back into Earth. This is because convection currents are driven by the movement of hot material rising to the surface and then cooling down, becoming denser and sinking back into the Earth. This continuous cycle of rising and sinking is what creates the convection current.

The Great Rift Valley in Africa is a ____________.
- Transform Boundary
- Divergent Boundary
- Convergent Boundary
Correct Answer

A. Divergent Boundary

Explanation

The Great Rift Valley in Africa is a divergent boundary. Divergent boundaries occur when two tectonic plates move away from each other, creating a gap or rift. In the case of the Great Rift Valley, the African Plate and the Arabian Plate are moving apart, causing the Earth's crust to stretch and crack. This movement has resulted in the formation of a long, deep valley with steep cliffs and escarpments. The valley is also characterized by volcanic activity, as magma rises to fill the gap created by the diverging plates.

The Andes mountain range of South America was formed at a ________.
- Convergent Boundary
- Divergent Boundary
- Hot Spot
- Transforming Boundary
Correct Answer

A. Convergent Boundary

Explanation

The Andes mountain range of South America was formed at a convergent boundary. Convergent boundaries occur when two tectonic plates collide, causing one plate to be forced beneath the other in a process called subduction. In the case of the Andes, the Nazca Plate is being forced beneath the South American Plate, resulting in the formation of the mountain range. This collision and subduction process leads to intense geological activity, including volcanic eruptions and the formation of large mountain ranges.

Rate this question:
15.

______ are formed when two continental plates collide.
- Volcanoes
- Strike-Slip faults
- Mountain Ranges
- Rift Valleys
Correct Answer

A. Mountain Ranges

Explanation

When two continental plates collide, immense pressure and force are exerted, causing the crust to buckle and fold. This process leads to the formation of mountain ranges. The collision between the plates causes the crust to uplift and create large, elevated landforms, such as the Himalayas or the Alps. These mountain ranges are characterized by their steep slopes, high peaks, and rugged terrain. Therefore, mountain ranges are the result of the collision between continental plates.

Rate this question:

The _______ is an example of a transform boundary.
- Appalachian Mountains
- Himalaya
- Mid-ocean Ridge
- San Andreas Fault
Correct Answer

A. San Andreas Fault

Explanation

The San Andreas Fault is an example of a transform boundary because it is a boundary where two tectonic plates slide past each other horizontally. Transform boundaries are characterized by intense seismic activity, as the plates grind against each other, causing earthquakes. The San Andreas Fault, located in California, is a well-known transform boundary where the Pacific Plate and the North American Plate meet. This fault line has experienced numerous earthquakes throughout history, making it a prime example of a transform boundary.

A __________ forms where two oceanic plates collide.
- Rift Valley
- Subduction Zone
- Transform Boundary
Correct Answer

A. Subduction Zone

Explanation

A subduction zone forms where two oceanic plates collide because one plate is forced beneath the other, sinking into the mantle. This process occurs because oceanic crust is denser than the underlying mantle. As the subducting plate sinks, it creates a deep trench on the ocean floor and can lead to volcanic activity and the formation of mountain ranges. This collision and subduction process is responsible for the creation of many geological features, such as the Pacific Ring of Fire.

Rate this question:
18.

What type of boundary occurs between the North American Plate and the Eurasian Plate?
- Transform Boundary
- Divergent Boundary
- Convergent oceanic-continental plate boundary
- Convergent oceanic-oceanic plate boundary
Correct Answer

A. Divergent Boundary

Explanation

A divergent boundary occurs between the North American Plate and the Eurasian Plate. This is because these two plates are moving away from each other, creating a gap where new crust is formed. This boundary is characterized by the presence of a mid-ocean ridge, such as the Mid-Atlantic Ridge, where magma rises to the surface and solidifies, creating new crust. This process of seafloor spreading is responsible for the formation of new oceanic crust and the widening of the Atlantic Ocean.

Rate this question:
19.

The name ______________ comes from two words that mean "all land"
- Seafloor
- Pangaea
- Continents
- Lithosphere
Correct Answer

A. Pangaea

Explanation

Pangaea is the correct answer because it is derived from two Greek words, "pan" meaning all and "gaea" meaning land. Pangaea refers to the supercontinent that existed millions of years ago, when all the Earth's landmasses were connected as one large landmass.

Rate this question:
20.

A(n) ________________ is an underwater mountain chain.
- Mid-ocean ridge
- Convergent Boundary
Correct Answer

A. Mid-ocean ridge

Explanation

A mid-ocean ridge is an underwater mountain chain that forms along divergent boundaries where tectonic plates are moving apart. As the plates separate, magma rises from the mantle and creates new crust, resulting in the formation of a ridge. These ridges can extend for thousands of kilometers and are characterized by volcanic activity, earthquakes, and the presence of hydrothermal vents. Therefore, a mid-ocean ridge is the correct answer as it accurately describes an underwater mountain chain.

Rate this question:
21.

New seafloor rock is continually being formed at mid-ocean ridges and old seafloor is continually removed at ocean trenches. If the rock on the continents is continually formed but not removed, how would the age of the oldest rocks on the continents compare with the age of the oldest rocks on the seafloor?
- Seafloor and Continent are the SAME age
- Seafloor is OLDER than the continent
- Continent is OLDER than the seafloor
Correct Answer

A. Continent is OLDER than the seafloor

Explanation

The given statement states that new seafloor rock is continually being formed at mid-ocean ridges and old seafloor is continually removed at ocean trenches. This process is known as seafloor spreading. On the other hand, the rock on the continents is continually formed but not removed. This means that the continents are not undergoing the same process of continuous renewal as the seafloor. Therefore, the age of the oldest rocks on the continents would be older than the age of the oldest rocks on the seafloor.

Rate this question:
22.

Which of the following examples (moving away from the mid-ocean ridge) is best represented by the diagram?
- Magnetic north and Geographic north have always aligned
- Magnetic north and Geographic south have always aligned
- Magnetic north alternates between the geographic north and south poles
- There has never been a changed in the magnetic north pole
Correct Answer

A. Magnetic north alternates between the geographic north and south poles

Explanation

The diagram represents the scenario where the magnetic north alternates between the geographic north and south poles. This means that over time, the magnetic north pole has shifted and moved between the two geographic poles. This is supported by the fact that the question mentions "moving away from the mid-ocean ridge," indicating a shift in the magnetic field away from the mid-ocean ridge.

Rate this question:
23.

Where is the oldest rock on the seafloor located?
- At the Mid-ocean ridge
- Far from the Mid-ocean ridge
- Half way between the mid-ocean ridge and a trench
Correct Answer

A. Far from the Mid-ocean ridge

Explanation

The correct answer is "Far from the Mid-ocean ridge." This is because the oldest rock on the seafloor is found in areas that are farther away from the mid-ocean ridge. The mid-ocean ridge is where new oceanic crust is formed through volcanic activity, so the rocks found there are relatively young. As the crust moves away from the ridge, it becomes older, and the oldest rocks are found in areas that are farthest from the ridge.

Rate this question:
24.

What type of plate boundary is represented in each of these pictures?
- Divergent
- Convergent
- Transform
Correct Answer

A. Convergent

Explanation

The given answer, "Convergent," suggests that the type of plate boundary represented in the pictures is a convergent boundary. A convergent boundary occurs when two tectonic plates collide and move towards each other. This collision often leads to the formation of mountains, volcanoes, or trenches, depending on the type of plates involved. The answer implies that the pictures show evidence of such converging plates and the associated geological features.

What living fossil attempted to help Alfred Wegener convice other scientist that the theory of plate tectonics was real?
- Mr. Reed
- Jimmy Buffet
- Harrison Ford
- Rex Morgan
Correct Answer

A. Mr. Reed

Explanation

Mr. Reed is the correct answer because he is a living fossil, meaning he is a person who has been alive for a very long time and has witnessed the changes in the Earth's crust. Alfred Wegener's theory of plate tectonics suggests that the Earth's crust is made up of several large plates that move over time. Mr. Reed, being a living fossil, would have experienced these movements and could provide evidence to support Wegener's theory. Jimmy Buffet, Harrison Ford, and Rex Morgan are not relevant to the theory of plate tectonics.

The deepest place on Earth is the Mariana Trench.
- True
- False
Correct Answer

A. True

Explanation

The Mariana Trench is indeed the deepest place on Earth. Located in the western Pacific Ocean, it reaches a depth of approximately 36,070 feet (10,994 meters). This trench is formed by the collision of two tectonic plates, the Pacific Plate and the Philippine Sea Plate. The extreme depth of the Mariana Trench is a result of this tectonic activity, making it the lowest point on Earth's surface.

Rate this question:
27.

What is the name of the process that "pulls" the Earths crust down into the mantle?
- Transforming
- Subduction
- Vulcanism
- Recycling
Correct Answer

A. Subduction

Explanation

Subduction is the correct answer because it refers to the process where one tectonic plate moves beneath another and sinks into the Earth's mantle. This process occurs at convergent plate boundaries, where two plates collide. As the denser plate sinks into the mantle, it pulls the Earth's crust down with it, causing subduction. This process is responsible for various geological phenomena, such as the formation of mountain ranges, volcanic activity, and the recycling of old crust material back into the mantle.

Rate this question:

Scientists have observed that the plates move at rates ranging from 2 cm to 12 cm per_____.
- Century
- Decade
- Day
- Year
Correct Answer

A. Year

Explanation

Scientists have observed that the plates move at rates ranging from 2 cm to 12 cm per year. This suggests that the movement of tectonic plates is a slow and gradual process, occurring over long periods of time. By studying the movement of these plates, scientists can gain insights into the dynamics of the Earth's crust and better understand geological processes such as earthquakes and volcanic activity.

Plates of the lithosphere float on Earth's thick, plastic like layer called the ____________.
- Crust
- Asthenosphere
- Core
- Atmosphere
Correct Answer

A. Asthenosphere

Explanation

The lithosphere, which consists of the Earth's crust and the upper part of the mantle, floats on the asthenosphere. The asthenosphere is a semi-fluid layer beneath the lithosphere that behaves like a plastic material. This allows the lithospheric plates to move and interact with each other. The core is the innermost layer of the Earth, while the atmosphere is the layer of gases surrounding the planet.

The _________are mountains on the northern most boundary of India formed by the collision of the Indo-Australian Plate and the Eurasian Plate
- Alps
- Rockies
- Himalaya
- Appalachian
Correct Answer

A. Himalaya

Explanation

The Himalaya mountains are formed by the collision of the Indo-Australian Plate and the Eurasian Plate. This collision caused the crust to buckle and fold, resulting in the formation of the highest mountain range in the world. The Himalayas are located on the northernmost boundary of India and stretch across several countries, including Nepal, Bhutan, and Tibet. They are known for their majestic peaks, including Mount Everest, and are a popular destination for climbers and trekkers from around the world.

Rate this question:

The presence of the same ___________on several continents supports the hypothesis of continental drift.
- Fossils
- Rock structures
- Fossils and rock structures
Correct Answer

A. Fossils and rock structures

Explanation

The presence of the same fossils and rock structures on several continents supports the hypothesis of continental drift because it suggests that these continents were once connected and have since moved apart. Fossils and rock structures are unique to specific regions, so finding the same ones on different continents indicates that these continents were once part of a larger landmass. This evidence aligns with the theory of continental drift, which proposes that the Earth's continents were once joined together in a single supercontinent called Pangaea and have since drifted apart over millions of years.

Rate this question:
32.

The boundary between two plates colliding together is called a(n) ___________.
- Divergent Boundary
- Convergent Boundary
- Transform Boundary
- Lithosphere
Correct Answer

A. Convergent Boundary

Explanation

A convergent boundary refers to the boundary where two tectonic plates collide with each other. This collision can result in various geological phenomena such as the formation of mountains, earthquakes, and volcanic activity. The convergence of the plates can occur in three different ways: oceanic-oceanic convergence, oceanic-continental convergence, and continental-continental convergence. In each case, the collision leads to the subduction of one plate beneath the other or the formation of a mountain range. Therefore, a convergent boundary is the correct term to describe the boundary between two plates colliding together.

Rate this question:
33.

Continental drift states that continents have moved _______ to their current location.
- Very Little
- Slowly
- Quickly
Correct Answer

A. Slowly

Explanation

Continental drift states that continents have moved slowly to their current location. This theory, proposed by Alfred Wegener, suggests that the Earth's continents were once joined together in a single landmass called Pangaea, which gradually broke apart and drifted to their present positions over millions of years. The movement of continents is believed to be driven by the slow motion of tectonic plates, which are large pieces of the Earth's lithosphere that float on the semi-fluid asthenosphere beneath them. This gradual movement of continents over time has resulted in the current distribution of landmasses on Earth.

Rate this question:
34.

______ currents inside Earth are currently the best explanation for tectonic plate motion.
- Vertical
- Convection
- Horizontal
- None of the answers are correct
Correct Answer

A. Convection

Explanation

Convection currents inside Earth are currently the best explanation for tectonic plate motion. Convection is the transfer of heat through the movement of a fluid, in this case, the molten rock in the Earth's mantle. As the molten rock heats up, it becomes less dense and rises towards the surface, creating a convection current. As it cools, it becomes more dense and sinks back down. This continuous cycle of rising and sinking creates a circular motion, which is believed to be the driving force behind the movement of tectonic plates on the Earth's surface.

Rate this question:
35.

Of the possibilities listed below, active volcanoes are most likely to form at ___________.
- Transform Boundaries
- Convergent continental-continental boundaries
- The center of continents
- Convergent oceanic-continental boundaries
Correct Answer

A. Convergent oceanic-continental boundaries

Explanation

Convergent oceanic-continental boundaries are most likely to form active volcanoes. These boundaries occur where an oceanic plate collides with a continental plate. The denser oceanic plate is forced beneath the less dense continental plate in a process called subduction. As the oceanic plate sinks into the mantle, it begins to melt, creating magma. This magma then rises to the surface, causing volcanic activity. This is why convergent oceanic-continental boundaries are the most likely location for the formation of active volcanoes.

Alfred Wegener believed that the ____________ were once all joined.
- Seafloor
- Pangaea
- Continents
- Lithosphere
Correct Answer

A. Continents

Explanation

Alfred Wegener believed that the continents were once all joined. This theory, known as continental drift, suggests that the continents were once part of a single supercontinent called Pangaea. Wegener proposed that over time, the continents drifted apart to their current positions. This idea was supported by evidence such as the fit of the continents' coastlines, matching rock formations, and fossil records. Wegener's theory revolutionized our understanding of Earth's geological history and laid the foundation for the modern theory of plate tectonics.

Rate this question:
37.

One plate can be forced under another plate at a _________________.
- Mid-ocean ridge
- Convergent Boundary
Correct Answer

A. Convergent Boundary

Explanation

At a convergent boundary, two tectonic plates are moving towards each other. When one plate is forced under another plate, it is known as subduction. This process occurs because the denser plate sinks into the mantle beneath the less dense plate. This subduction can result in the formation of trenches, volcanic activity, and the creation of mountain ranges. Therefore, a convergent boundary is the correct answer for the given question.

Rate this question:
38.

The main points of evidence Wegener used for the theory of __________ are fossils, rocks, and climate clues.
- Mid-ocean ridge
- Convergent Boundary
- Continental Drift
Correct Answer

A. Continental Drift

Explanation

Wegener used fossils, rocks, and climate clues as evidence for the theory of Continental Drift. Fossils found on different continents were similar, suggesting that the continents were once connected. The alignment of rock formations across continents also supported the idea of continental movement. Additionally, Wegener observed that certain climate clues, such as glacial deposits, matched up when continents were brought together. All of this evidence led Wegener to propose the theory of Continental Drift.

Wegener used the fact that South America and Africa fit together like puzzle pieces. What are some of the other clues he used to support the theory plate tectonics?
- Plant and animal fossils
- Climate clues
- Similar land masses
- All the answers are correct
Correct Answer

A. All the answers are correct

Explanation

Wegener used various clues to support the theory of plate tectonics. One of the clues was the fit of South America and Africa, which suggested that they were once connected. He also considered plant and animal fossils found on different continents, which indicated that these continents were once joined and had similar ecosystems. Additionally, he analyzed climate clues, such as glacial deposits and coal deposits, which provided evidence of past climates and their connection between different land masses. All of these clues together supported Wegener's theory of plate tectonics.

What landform is created at the boundary between two oceanic plates?
- Trench
- Mountain range
- Mid ocean ridge
Correct Answer

A. Trench

Explanation

At the boundary between two oceanic plates, a trench is created. Trenches are long, narrow depressions in the ocean floor that form when one oceanic plate is forced beneath another in a process called subduction. This occurs at convergent plate boundaries where two plates are moving towards each other. As the denser oceanic plate sinks into the mantle, it creates a deep trench on the ocean floor. Trenches are typically associated with intense seismic activity and are often the sites of earthquakes and volcanic activity.
