• sediment

Which type of igneous material cools fastest?

• lava

• magma

• sediments

• sandstone

A rock that has cooled fast and may look like glass.

• igneous

• metamorphic

• sedimentary

• sediment

Movement of the Earth's tectonic plates creates extreme _____ below Earth's surface.

• compaction/cementation

• weathering/erosion

• heat/pressure

• explosions/exchanges

What process is used to form sedimentary rocks?

• Lava cools and hardens to form a rock.
• Weathering, Erosion, Deposition, Compaction, Cementation
• Extreme heat and pressure from inside the Earth turn rocks into new rocks.
• Magma trapped under the Earth's surface cools and solidifies.
