The Rock Cycle Review

The Rock Cycle Review

Multiple Choice

There are three major types of rocks: igneous, sedimentary, and metamorphic. These rock types may change from one type to another over time due to varying conditions.

What important factor transforms metamorphic and igneous rocks to sedimentary rocks?

• agents of weathering

• extreme pressure

• intense heat beneath Earth’s crust

• rapid cooling beneath Earth’s crust

Multiple Choice

A student lists three processes that occur to a rock.

Assuming the rock finishes a fourth process of melting and slow cooling, what are the classifications of the rock after the first and fourth processes?

• 1: metamorphic; 4: sedimentary

• 1: metamorphic; 4: intrusive igneous

• 1: intrusive igneous; 4: sedimentary

• 1: intrusive igneous; 4: metamorphic

Multiple Choice

A student sketches three figures.

Which process is most likely occurring in all three figures?

• erosion

• rock formation

• seafloor spreading

• volcanic eruption

Multiple Choice

Which processes would cause granite, an igneous rock, to form schist, a metamorphic rock?

• melting and weathering

• weathering and erosion

• cooling and hardening

• heat and pressure

Multiple Choice

A student examines a cross section of an area with a rock layer labeled X.

What is the best description of rock layer X?

• It is an igneous rock layer that is older than the sedimentary rock around it.

• It is an igneous rock layer that is younger than the sedimentary rock around it.

• It is a sedimentary rock layer that is older than the igneous rock around it.

• It is a sedimentary rock layer that is younger than the igneous rock around it.

Multiple Choice

The image shows a section of rock layers having experienced a variety of events.

Which type of rock most likely composes layer E?

• igneous

• metamorphic

• molten

• sedimentary

Multiple Choice

Which condition is necessary for metamorphic rocks to form?

• constant weathering and erosion

• extreme pressure and heating

• rapid burial of sediments

• slow cooling of magma

Multiple Choice

How are sedimentary rocks made?

• Magma or lava is cooled.

• Materials are pressed together.

• Chemical reactions change minerals.

• Earthquakes cause small pieces to fall.

Multiple Choice

In order for boulders to become sediments, the boulders must first be

• heated and melted.

• weathered and eroded.

• recrystallized.

• buried.

Multiple Choice

The diagram is a geologic cross section showing sedimentary rock layers with an igneous intrusion.

Which layer of rock is the youngest ?

• layer W

• layer X

• layer Y

• layer Z

Multiple Choice

The image shows the rock cycle and the associated processes leading to the formation of two kinds of rocks labeled rock 1 and rock 2.

What are the types of rocks formed?

• Rock 1 is an intrusive igneous, and rock 2 is an extrusive sedimentary.

• Rock 1 is an extrusive igneous, and rock 2 is an intrusive sedimentary.

• Rock 1 is an intrusive sedimentary, and rock 2 is an extrusive sedimentary.

• Rock 1 is an intrusive igneous, and rock 2 is an extrusive igneous.
