Front

What are the three main types of rocks?

Back

Igneous, Sedimentary, and Metamorphic.

Front

How are igneous rocks formed?

Back

Igneous rocks are formed from the cooling and solidification of magma or lava.

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 Earth's surface.

Front

What are sedimentary rocks made of?

Back

Sedimentary rocks are made of sediments that are compressed and cemented together over time.

Front

How are metamorphic rocks formed?

Back

Metamorphic rocks are formed from existing rocks that undergo changes due to high pressure and temperature.

Front

What is an example of an extrusive igneous rock?

Back

Basalt is an example of an extrusive igneous rock.

Front

What is an example of an intrusive igneous rock?

Back

Granite is an example of an intrusive igneous rock.

Front

What is limestone primarily composed of?

Back

Limestone is primarily composed of calcium carbonate.

Front

What process leads to the formation of sedimentary rocks?

Back

Sedimentation, which involves the deposition, compaction, and cementation of sediments.

Front

Where are metamorphic rocks commonly found?

Back

Metamorphic rocks are commonly found in mountain ranges and areas of tectonic activity.
