The Rock Cycle and Types of Rocks Quiz

Which process primarily forms igneous rocks?

• Compaction and cementation

• Cooling and solidification of magma or lava

• High pressure and temperature without melting

• Weathering, erosion, and deposition

What is the main characteristic that distinguishes metamorphic rocks from other types of rocks?

• They are primarily formed by the cooling of magma.

• They consist of layers and fossils.

• They have been altered by heat, pressure, or chemically active fluids.

• They are composed of grains that are cemented together.

Which type of sedimentary rock is formed from the remains of plants or animals?

• Clastic

• Chemical

• Organic

• Metamorphic

In the rock cycle, what process transforms sediment into sedimentary rock?

• Melting

• Erosion

• Compaction and cementation

• Metamorphism

Which of the following is an example of an igneous rock?

• Slate

• Limestone

• Granite

• Marble

What is the main agent that drives the rock cycle?

• The Sun

• Gravity

• Plate tectonics

• The Moon

Which of the following textures would you most likely find in an igneous rock that cooled quickly?

• Coarse-grained

• Fine-grained

• Foliated

• Non-foliated

During metamorphism, what does the term "foliation" refer to?

• The process of forming layers

• The alignment of minerals within the rock

• The melting of the rock

• The cooling and solidification process

Which process is responsible for the formation of clastic sedimentary rocks?

• Precipitation of minerals from water

• Cooling and solidification of lava

• Weathering, erosion, and deposition

• High pressure and temperature

What is a key feature used to identify igneous rocks?

• The presence of fossils

• The size of the mineral grains

• The presence of layers
