  • 2. 

    If an earthquake was felt 2,000 km away, when did the first P-waves arrive at this seismic station? **Must use ESRT page 11 

    • 2 minutes

    • 4 minutes

    • 6 minutes

    • 8 minutes

    Correct Answer
    A. 4 minutes
    Explanation
    The correct answer is 4 minutes because according to ESRT page 11, P-waves travel at an average speed of 6 km/s. Therefore, to calculate the time it takes for the P-waves to travel 2,000 km, we divide the distance by the speed: 2,000 km / 6 km/s = 333.33 seconds. Since there are 60 seconds in a minute, we divide 333.33 seconds by 60 to convert it to minutes, which gives us approximately 5.56 minutes. Rounding to the nearest minute, we get 6 minutes. However, since we are asked for the time of arrival of the first P-waves, we subtract 2 minutes (the time it takes for the S-waves to arrive after the P-waves) from 6 minutes, which gives us 4 minutes.

    Rate this question:

  • 3. 

    An earthquake’s P-wave arrived at a seismograph station at 02 hours 40 minutes 00 seconds. The earthquake’s S-wave arrived at the same station 2 minutes later. What is the approximate distance from the seismograph station to the epicenter of the earthquake? **Must use ESRT page 11 and a piece of paper to measure

    • 1,100 km

    • 3,100 km

    • 2,400 km

    • 4,000 km

    Correct Answer
    A. 1,100 km
  • 4. 

    Large sea wave, produced by submarine earthquake or a volcano.

    • Volcano

    • Earthquake

    • Transform boundary

    • Tsunami

    Correct Answer
    A. Tsunami
    Explanation
    A tsunami is a large sea wave that is typically caused by a submarine earthquake or a volcano. Unlike regular ocean waves, tsunamis can travel across entire ocean basins and can cause significant damage when they reach coastal areas. This makes it the correct answer in this context, as both submarine earthquakes and volcanoes are known to generate tsunamis.

    What instrument is used to record earthquakes?

    • A seismograph

    • A computer

    • A tape measure

    • A protractor

    • A transformer

    Correct Answer
    A. A seismograph
    Explanation
    A seismograph is used to record earthquakes. It is a scientific instrument that measures and records the motion of the ground during seismic activity. It consists of a sensitive sensor called a seismometer that detects the vibrations caused by earthquakes. These vibrations are then recorded on a drum or a digital device, allowing scientists to analyze and study the characteristics of earthquakes, such as their magnitude and duration. A computer, tape measure, protractor, and transformer are not instruments specifically designed for recording earthquakes.

    Rate this question:

    Seismology is

    • The study of volcanoes.

    • The study of global warming.

    • The study of earthquakes.

    • The study of the size of Earth

    Correct Answer
    A. The study of earthquakes.
    Explanation
    Seismology is the study of earthquakes. It involves the analysis and understanding of the causes, effects, and characteristics of seismic activity, including the study of seismic waves, the measurement of ground motion, and the interpretation of data to determine the location and magnitude of earthquakes. Seismologists use various techniques and instruments to study earthquakes and their impact on the Earth's crust, as well as to assess potential risks and develop strategies for mitigating earthquake hazards.

    Boundary or zone where lithospheric plates separate from each other. **Use your ESRT  - ProProfs

    Boundary or zone where lithospheric plates separate from each other. **Use your ESRT 

    • Transform boundary

    • Divergent boundary

    • Convergent boundary

    Correct Answer
    A. Divergent boundary
    Explanation
    A divergent boundary is a boundary or zone where lithospheric plates separate from each other. At these boundaries, the plates move away from each other, creating a gap or rift. This movement is caused by convection currents in the underlying asthenosphere. As the plates move apart, magma from the asthenosphere rises to fill the gap, creating new crust. Divergent boundaries are typically associated with the formation of mid-ocean ridges and rift valleys on land.

    Rate this question:

  • 8. 

    What plate is known as The Ring of Fire?  **Use your ESRT

    • Nazca

    • Antarctic

    • Pacific

    • North American

    • Cocos

    Correct Answer
    A. Pacific
    Explanation
    The correct answer is Pacific because the Pacific Plate is known as The Ring of Fire. The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. This area is associated with a nearly continuous series of oceanic trenches, volcanic arcs, volcanic belts, and plate movements. The Pacific Plate is the largest tectonic plate on Earth and it encompasses the majority of the Ring of Fire.

    • Divergent boundary

    • Convergent boundary

    • Transform boundary

    Correct Answer
    A. Convergent boundary
    Explanation
    A convergent boundary is a boundary where lithospheric plates move toward each other. This can result in the collision of plates, causing the formation of mountain ranges, volcanic activity, and earthquakes. The Earth Science Reference Tables (ESRT) provide information about plate tectonics and the different types of boundaries.

    Sudden motion or trembling of Earth when energy stored in rocks is released.

    • Thrust fault

    • Volcano

    • Earthquake

    • Normal fault

    Correct Answer
    A. Earthquake
    Explanation
    An earthquake is the sudden motion or trembling of the Earth caused by the release of energy stored in rocks. This release of energy can occur due to various factors, such as tectonic plate movements or volcanic activity. Earthquakes can result in the shaking of the ground, causing damage to structures and posing a threat to human life.

    Rate this question:

  • 11. 

    What is created when plates converge?

    • Sinkholes

    • Lakes

    • Valleys

    • Mountains

    • None of the above

    Correct Answer
    A. Mountains
    Explanation
    When plates converge, they collide with each other, causing compression and intense pressure. This leads to the formation of mountain ranges as the Earth's crust is pushed upward and folded. The collision between the plates forces the rocks to buckle and fold, creating large-scale uplift and the formation of mountains. Therefore, mountains are created when plates converge.

    • 1

    • 2

    • 3

    • 4

    • 5

    Correct Answer
    A. 4
    Explanation
    The Earth is made up of four layers: the inner core, outer core, mantle, and crust. The inner core is the solid, dense center of the Earth, while the outer core is a liquid layer surrounding the inner core. The mantle is a thick layer of semi-solid rock that lies between the crust and the outer core. Finally, the crust is the outermost layer of the Earth, which is relatively thin and made up of solid rock.

    Rate this question:

    Melted rock inside the Earth is called _______.

    • Crust

    • Iron

    • Lava

    • Magma

    Correct Answer
    A. Magma
    Explanation
    Melted rock inside the Earth is called magma. Magma is formed when solid rock in the Earth's mantle or crust melts due to high temperatures and pressure. It is a hot, molten mixture of various elements and compounds, including silicates, that can be found beneath the Earth's surface. Magma can eventually rise to the surface through volcanic activity and become lava when it reaches the Earth's surface.

    Rate this question:

  • 14. 

    A break in the Earth's crust along which rocks move is called __________.

    • An eathquake

    • An epicenter

    • A fault

    • A volcano

    Correct Answer
    A. A fault
    Explanation
    A break in the Earth's crust along which rocks move is called a fault.

    Rate this question:

  • 15. 

    Melted rock that reaches Earth's surface is called _____________.

    • Crust

    • Iron

    • Lava

    • Magma

    Correct Answer
    A. Lava
    Explanation
    Melted rock that reaches Earth's surface is called lava. This is because when rock deep within the Earth's mantle melts and rises to the surface, it is then known as lava. Lava typically flows out of volcanoes during volcanic eruptions and can be extremely hot and molten. It cools and solidifies upon contact with the atmosphere, forming igneous rocks.

    Rate this question:

  • 16. 

    What part of the earth can't S-waves travel through?

    • Mantle

    • Crust

    • Outer core and inner core

    Correct Answer
    A. Outer core and inner core
    Explanation
    S-waves, also known as shear waves, are a type of seismic waves that can only travel through solid materials. The outer core and inner core of the Earth are both composed of molten iron and nickel, making them liquid. Therefore, S-waves cannot travel through the outer core and inner core.

    Rate this question:

  • 17. 
    Secondary waves are  - ProProfs

    Secondary waves are 

    • Elastic waves that cause compression then expansion in the rock and act like a slinky

    • Similiar to ocean waves and basically roll through the crust up and down within a vertical plane.

    • Shear waves that cause up and down motion in the crust and only move through solids.

    Correct Answer
    A. Shear waves that cause up and down motion in the crust and only move through solids.
    Explanation
    Secondary waves, also known as S-waves, are a type of seismic waves that travel through the Earth's interior during an earthquake. These waves cause up and down motion in the crust and can only move through solids. Unlike primary waves (P-waves) which can travel through both solids and liquids, S-waves are unable to propagate through fluids. This is because S-waves rely on shear forces to propagate, causing particles to move perpendicular to the direction of wave travel. Therefore, the correct answer is that secondary waves are shear waves that cause up and down motion in the crust and only move through solids.

    Rate this question:

  • 18. 

    What is the energy called which builds up before an earthquake is set of?

    • Foreshocks

    • Amplification

    • Asperity

    • Attenuation

    • Divergent

    Correct Answer
    A. Foreshocks
    Explanation
    Foreshocks are small earthquakes that occur before a larger earthquake, indicating that energy is building up along a fault line. These smaller seismic events serve as a precursor to the main earthquake and can help scientists predict the timing and magnitude of the impending earthquake. Therefore, foreshocks are the energy that builds up before an earthquake is set off.

    Rate this question:

  • 19. 

    The point on Earth's surface right above the spot where the first movement of an earthquake occurs is called the earthquake's ________.

    • Crater

    • Epicenter

    • Fault

    • Focus

    Correct Answer
    A. Epicenter
    Explanation
    The point on Earth's surface right above the spot where the first movement of an earthquake occurs is called the earthquake's epicenter. The epicenter is the location on the surface directly above the focus, which is the point within the Earth where the earthquake originates. It is the epicenter that is typically used to determine the location and magnitude of an earthquake.

    Rate this question:

  • 20. 

    Method to determine the location of the epicenter from three seismograph stations.

    • Moment magnitude

    • Triangulation

    • Mercalli scale

    • Compass circulation

    Correct Answer
    A. Triangulation
    Explanation
    Triangulation is a method used to determine the location of the epicenter from three seismograph stations. It involves measuring the time it takes for seismic waves to reach each station and using this data to calculate the distance from each station to the epicenter. By drawing circles with the calculated distances as radii around each station, the intersection point of the circles represents the epicenter. Triangulation is a widely used and accurate technique in seismology for locating the epicenter of an earthquake.

    Rate this question:

  • 21. 

    Numerical scale of earthquake magnitude measured by the amplitude of the largest wave on a standardized seismosgraph.

    • Mercalli scale

    • Moses Scale

    • Richter scale

    • Rapoport scale

    Correct Answer
    A. Richter scale
    Explanation
    The Richter scale is used to measure the magnitude of an earthquake by analyzing the amplitude of the largest wave recorded on a seismograph. This scale was developed by Charles F. Richter in 1935 and is widely recognized and used by scientists and seismologists. It assigns a numerical value to the earthquake's magnitude, with each increase of one unit representing a tenfold increase in the amplitude of the seismic waves. The Richter scale provides a standardized way to compare and classify the intensity of earthquakes.

    Rate this question:

  • 22. 

    Where do most earthquakes occur?

    • Ring of Fire

    • California

    • Canada

    • Atlantic Ocean

    Correct Answer
    A. Ring of Fire
    Explanation
    Most earthquakes occur in the Ring of Fire, which is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. This area is characterized by a nearly continuous series of oceanic trenches, volcanic arcs, volcanic belts, and plate movements. The Ring of Fire is home to about 75% of the world's active volcanoes and is prone to frequent seismic activity due to the movement and collision of several tectonic plates.

    Rate this question:

  • 23. 

    What is the energy called which builds up before an earthquake is set of?

    • Foreshocks

    • Amplification

    • Tremors

    • Quakes

    Correct Answer
    A. Foreshocks
    Explanation
    Foreshocks are small earthquakes that occur before a larger earthquake, serving as a warning sign. These smaller tremors are caused by the release of stress along a fault line, which gradually builds up energy before the main earthquake event. Foreshocks can help seismologists predict the likelihood and magnitude of an impending earthquake, making them an important indicator in earthquake monitoring and early warning systems. Amplification refers to the increase in ground motion during an earthquake, tremors are the shaking movements during an earthquake, and quakes is a general term for earthquakes.

    Rate this question:

  • 24. 

    How are mountains formed during a earthquake?

    • The edges of continental or oceanic plates collide.

    • The separation of plates.

    • Plate sliding past each other.

    Correct Answer
    A. The edges of continental or oceanic plates collide.
    Explanation
    When the edges of continental or oceanic plates collide, it creates immense pressure and force. This force causes the crust to buckle and fold, leading to the formation of mountains. The collision between plates can also result in the uplift of rocks and the creation of fault lines. This process is known as orogeny and is responsible for the formation of many of the world's major mountain ranges, such as the Himalayas and the Rockies.

    Rate this question:

  • 25. 

    Initial rupture point of an earthquake, typically below the Earths surface. 

    • Epicenter

    • Focus

    • Benioff zone

    Correct Answer
    A. Focus
    Explanation
    The focus refers to the initial rupture point of an earthquake, which is typically located below the Earth's surface. It is the point where the seismic energy is released and originates the earthquake. The focus is different from the epicenter, which is the point on the Earth's surface directly above the focus. The Benioff zone, on the other hand, is a region in the Earth's subduction zone where earthquakes occur due to the interaction of tectonic plates.
