Rock Classification Quiz

Igneous rock forms in regions where –

• rock is heated to melting point then cooled to a solid.

• metallic minerals are put under extreme pressure.

• a river deposits sand and mud over a long time.

• evidence of organisms is becoming fossilized.

Sedimentary rocks will most likely form an environment where -

• two land masses are colliding.

• liquid rock is hardening into a solid.

• minerals are being created under pressure.

• particles of rocks are accumulating.

Which of the following processes produce metamorphic rocks?

• rapid burial

• gradual cooling

• regular deposition

• extreme pressure

Scientists classify igneous, metamorphic, and sedimentary rocks based on their –

• shape

• color

• formation

• usefulness

Which of the following best describes the processes that form igneous rocks?

• Deposition and cementation

• Heating and extreme pressure

• Crystallization and solidification

• Erosion and compaction

Metamorphic rocks are different from igneous and sedimentary rocks in that metamorphic rocks form -

• when liquid rock freezes into a solid.

• by magma rising from Earth’s core.

• from existing rock that has been changed.

• by layering minerals of different sizes.

Sedimentary rock can be changed into igneous rock if sediments are –

• compacted

• deposited

• weathered

• melted

Igneous and sedimentary rocks could each be changed into metamorphic rock if they are changed by -

• weathering

• organisms

• pressure

• cementation

What type of rock is this?

• sedimentary

• metamorphic

• igneous

• magical
