The size of the crystals in an igneous rock is dependent on

• how fast or slow the lava cools

• the amount of heat and pressure

• the amount of solute

• the type of magma

An example of an igneous rocks with large crystals that are clearly visible is

• basalt

• granite

• obsidian

• limestone

An igneous rock that forms inside the earth is called

• sedimentary

• metamorphic

• extrusive igneous

• Intrusive igneous

Sedimentary rocks are formed from

• cooling of magma or lava

• heat and pressure

• weathering and erosion

• solute cooling

The final step of creating sedimentary rocks is when the sediment is "glued" together. This is known as ______________

• compaction

• cementing

• deposition

• erosion

Lava that cools quickly on the surface of the earth forms

• extrusive igneous rock

• intrusive igneous rock

• granite

• metamorphic rock

Metamorphic rocks are formed from

• cooling of magma or lava

• weathering and erosion

• heat and pressure

• solutions
