What is an igneous rock?

Back

Igneous rock is formed when magma cools and hardens.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed when existing rocks are changed by heat and pressure.

Front

What is the process that changes granite into gneiss?

Back

Heat and pressure.

Front

What is the role of heat and pressure in the rock cycle?

Back

Heat and pressure can transform sedimentary and igneous rocks into metamorphic rocks.

Front

What is an example of an igneous rock?

Back

Granite is an example of an igneous rock.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly underground, while extrusive igneous rocks form from lava that cools quickly on the surface.
