Minerals and Rock Cycle Review

Front

What is the process by which metamorphic rocks are formed?

Back

Metamorphic rocks are formed when sedimentary and igneous rocks change over time under heat and pressure.

Front

What are the two main processes responsible for changing sediments into sedimentary rock?

Back

Compaction and cementation.

Front

How is a mineral's hardness measured?

Back

A mineral's hardness is measured on the Mohs scale.

Front

What is the term for the transformation of rocks from one type to another?

Back

The rock cycle.

Front

What must occur for sedimentary rock to form?

Back

Compaction.

Front

What type of rock is formed from the cooling and solidification of magma or lava?

Back

Igneous rock.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things.

What role does pressure play in the formation of metamorphic rocks?

Back

Pressure causes the minerals in the original rock to recrystallize, leading to the formation of metamorphic rocks.

Front

What is the significance of the rock cycle in geology?

Back

The rock cycle illustrates how rocks are continuously transformed between igneous, sedimentary, and metamorphic forms.
