- A.
Igneous
- B.
Metamorphic
- C.
Sedimentary
Correct Answer
C. SedimentaryExplanation
Sandstone is a sedimentary rock because it is formed from the accumulation and compaction of sand particles over time. Sedimentary rocks are formed through the processes of weathering, erosion, deposition, and lithification. In the case of sandstone, the sand particles are compacted and cemented together to form a solid rock.Rate this question:

According to the rock cycle diagram, what type of rock can a metamorphic rock turn into?
- A.
Igneous
- B.
Metamorphic
- C.
Sedimentary
- D.
All 3 types
Correct Answer
D. All 3 typesExplanation
Metamorphic rocks can turn into all three types of rocks: igneous, sedimentary, and metamorphic. This is because the rock cycle is a continuous process where rocks are constantly changing from one type to another over long periods of time. Metamorphic rocks can be subjected to heat and pressure, causing them to melt and become igneous rocks. They can also be weathered and eroded, forming sediment that can then be compacted and cemented to become sedimentary rocks. Additionally, metamorphic rocks can undergo further metamorphism, resulting in the formation of new metamorphic rocks.Rate this question:

According to the rock cycle diagram, must happen for sedimentary rock to form?
- A.
Solidification
- B.
Heat and/or Pressure
- C.
Burial and Cementation
- D.
Melting
Correct Answer
C. Burial and CementationExplanation
Burial and cementation must happen for sedimentary rock to form. Burial refers to the process of sediment being deposited and accumulating over time. This can occur in bodies of water, such as rivers or oceans, where sediment settles and compacts. Cementation, on the other hand, refers to the process of minerals, such as calcite or silica, filling the spaces between sediment particles and binding them together. This process helps to solidify the sediment into a cohesive rock. Therefore, both burial and cementation are necessary steps in the formation of sedimentary rock according to the rock cycle diagram.Rate this question:

Fossils that are further BELOW the surface are ___________ than fossils near the surface.
- A.
Older
- B.
Younger
- C.
The same age
- D.
Cannot tell from the information
Correct Answer
A. OlderExplanation
Fossils that are further below the surface are older than fossils near the surface. This is because the process of fossilization occurs over time as layers of sediment build up and compress the remains of organisms. As new layers are added on top, older layers are pushed deeper into the Earth's crust. Therefore, fossils found deeper in the ground have had more time to accumulate layers of sediment and are therefore older than those found near the surface.Rate this question:

Lava is a synonym for:
- A.
Intrusive igneous rock
- B.
Extrusive igneous rock
- C.
Sedimentary rock
- D.
Magma
Correct Answer
B. Extrusive igneous rockExplanation
Extrusive igneous rock is the correct answer because lava refers to molten rock that reaches the Earth's surface and cools quickly, forming solid rocks. This type of igneous rock is formed through volcanic activity and is characterized by its fine-grained texture due to rapid cooling. Intrusive igneous rock, on the other hand, forms beneath the Earth's surface and cools slowly, resulting in a coarse-grained texture. Sedimentary rock is formed through the accumulation and compaction of sediments, while magma is the molten rock beneath the Earth's surface.Rate this question:

Marble and Gneiss are examples of:
- A.
Igneous Rock
- B.
Sedimentary Rock
- C.
Metamorphic Rock
Correct Answer
C. Metamorphic RockExplanation
Marble and Gneiss are examples of metamorphic rock. Metamorphic rocks are formed through the transformation of pre-existing rocks under high temperatures and pressures. Marble is formed from limestone that has been subjected to intense heat and pressure, causing the calcite crystals to recrystallize and form a new rock with a distinct texture and appearance. Gneiss is formed from the metamorphism of existing rocks, such as granite, and is characterized by its banded appearance and foliated texture. Both marble and gneiss are examples of rocks that have undergone significant changes in their mineralogy and texture due to the geological processes of metamorphism.Rate this question:

A sedimentary rock can turn into an igneous rock by:
- A.
Burial and Deposition
- B.
Weathering and Erosion
- C.
Melting and Solidification
Correct Answer
C. Melting and SolidificationExplanation
When a sedimentary rock undergoes the process of melting and solidification, it can transform into an igneous rock. Melting occurs due to the high temperatures deep within the Earth's crust or mantle, causing the sedimentary rock to melt and become molten rock called magma. This magma then cools and solidifies, either underground or at the Earth's surface, forming a new rock with a crystalline structure known as an igneous rock. This process is responsible for the formation of many igneous rocks, such as granite and basalt.Rate this question:

'The process by which rocks change from one type to another over a period of time' refers to:
- A.
The Water Cycle
- B.
The Rock Cycle
- C.
Metamorphism
- D.
Evaporation
Correct Answer
B. The Rock CycleExplanation
The correct answer is the Rock Cycle. The rock cycle refers to the process by which rocks are transformed from one type to another over time. This process involves various geological processes such as weathering, erosion, deposition, compaction, and cementation. Through these processes, rocks can be broken down, transported, and reformed into different types of rocks, including sedimentary, igneous, and metamorphic rocks. The rock cycle is a continuous and dynamic process that occurs over millions of years and is driven by the Earth's internal heat, gravity, and external forces like water, wind, and ice.Rate this question:

What type of rock is this:
- A.
Igneous
- B.
Metamorphic
- C.
Sedimentary
Correct Answer
C. SedimentaryExplanation
This rock is classified as sedimentary because it is formed from the accumulation and compaction of sediments over time. Sedimentary rocks are typically composed of particles such as sand, silt, and clay that have been deposited by wind, water, or ice. These sediments are then compacted and cemented together to form solid rock.Rate this question:

How were these structures formed?
- A.
Erosion
- B.
The Rock Cycle
- C.
Weathering
- D.
Magma
Correct Answer
C. WeatheringExplanation
Weathering refers to the process of breaking down rocks and minerals on the Earth's surface. It is caused by various factors such as wind, water, temperature changes, and chemical reactions. Over time, these external forces cause the rocks to disintegrate and form new structures. This process is responsible for the formation of various landforms like canyons, cliffs, and caves. Therefore, weathering is the most likely explanation for the formation of these structures.Rate this question:

- A.
Igneous
- B.
Metamorphic
- C.
Sedimentary
- D.
Cannot tell from this information
Correct Answer
C. SedimentaryExplanation
This fossil is formed in sedimentary rock because sedimentary rocks are formed from the accumulation and consolidation of sediments, which can include the remains of plants and animals. Fossils are commonly found in sedimentary rocks because the process of sedimentation allows for the preservation of organic material. Igneous rocks are formed from the solidification of molten material, while metamorphic rocks are formed from the alteration of pre-existing rocks due to heat and pressure. Without further information, it is not possible to determine if the fossil is formed in igneous or metamorphic rock.Rate this question:

These rocks have most likely been smoothed and rounded from erosion in a:
- A.
River
- B.
Desert
- C.
Forest
Correct Answer
A. RiverExplanation
The rocks have most likely been smoothed and rounded from erosion in a river because rivers have the power to carry and transport sediment, including rocks, downstream. As the rocks are transported by the flowing water, they collide with each other and with the riverbed, causing abrasion and wearing down their rough edges. Over time, this constant movement and friction in the river water results in the rocks becoming smoother and more rounded.Rate this question:

This is pumice. What type of rock is pumice?
- A.
Metamorphic
- B.
Igneous
- C.
Sedimentary
- D.
Cannot tell from this information
Correct Answer
B. IgneousExplanation
Pumice is a type of rock that is formed from volcanic activity. It is created when lava with high levels of gas and water content is rapidly cooled and solidified. This rapid cooling process traps the gas bubbles within the rock, giving pumice its characteristic porous and lightweight texture. Since pumice is formed through volcanic processes, it is classified as an igneous rock.Rate this question:
