Rock Transformation

What are the three major types of rocks based on their formation?

• Igneous, Volcanic, and Sedimentary

• Igneous, Sedimentary, and Metamorphic

• Magmatic, Sedimentary, and Metamorphic

• Extrusive, Intrusive, and Metamorphic

How are igneous rocks formed?

• From sediments compressed over a long time.

• When existing rocks undergo change due to high temperature and pressure.

• When molten magma cools down and solidifies.

• From organic matter found on ocean beds.

What are sedimentary rocks primarily composed of?

• Molten lava and volcanic ash.

• Minerals, small pieces of plants, and other organic matter.

• Denser, more compact rocks.

• Only large rock fragments.

What is the process called when igneous and sedimentary rocks change due to high temperatures and pressures, transforming into denser, more compact rocks?

• Erosion

• Solidification

• Metamorphism

• Deposition
