Extrusive rock is magma that cools. Coarse grained materials since the cooling process is slow,

• True

• Mineral

Clastic sedimentary rocks formed from accumulation of clasts; little pieces of broken rocks and shell.

• True

• False

Contact happens on layers of rocks having contact with heat (magma).

• True

• False - Compact

Extrusive rock is lava that cool. Fined grained materials since the cooling process is fast.

• True

• False - Intrusive rock

Organic rocks are an example of metamorphic rock

• False - Sedimentary rock

• True

It happens on layers of rocks having contact with heat.

• Compaction

• Cementation

• Lithification

• Contact

It is the process that change pre-existing rocks into new forms because of increases in temperature and pressure.

• Weathering

• Metamorphism

• Rock Cycle

• Lithification

It is the breaking down of pre-existing rocks on the Earth surface.

• Lithification

• Weathering

• Compaction

• Cementation

It is the solid collection of mineral grains that grow and become cemented together.

• Metallic minerals

• Rock

Formed from hardening and crystallization of molten rocks.

• Igneous rocks

• Metamorphic rock
