What is an igneous rock?

Back

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

Front

What is a sedimentary rock?

Back

Sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles.

Front

What is a metamorphic rock?

Back

Metamorphic rocks are formed when existing rocks are changed by heat, pressure, or chemical processes.

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 foliation in metamorphic rocks?

Back

Foliation is the alignment of mineral grains in metamorphic rocks, resulting in a layered or banded appearance.

Front

What is an example of an organic sedimentary rock?

Back

An example of an organic sedimentary rock is limestone, which can form from the accumulation of shells and coral.

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form through the processes of weathering, erosion, deposition, compaction, and cementation of sediments.

What is the process of metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed into metamorphic rocks due to heat, pressure, and chemically active fluids.
