What must happen to a sedimentary rock in order for it to change into an igneous rock?

• It must be weathered and eroded.

• It must melt, then cool and harden.

• It must become cemented to other rocks.

• It must be put under pressure until new minerals form in it.

• Deposition

Why do metamorphic rocks rarely contain fossils?

• These rocks are formed underwater, and the water dissolves the fossils.

• The rock formation occurs from extremely hot magma deep inside the crust where organisms do no live.

• These rocks undergo extremely high pressure or temperature changes when formed, which would destroy fossils.

• These rocks are usually formed from extremely hot magma or with severe lava explosions, which would destroy fossils.

What is the only liquid layer of the Earth?

• Crust

• Mantle

• Inner Core

• Outer Core

Which of the following is a true statement about the rock cycle?

• Heat, pressure, cooling, weathering, erosion, and deposition change rock.

• The formation of rock within the cycle ends after metamorphic rocks form.

• Weathering occurs in igneous rocks but never in sedimentary or metamorphic.

• The rock cycle creates new rocks and destroys old rock
