Has large crystals because of slow cooling

• sedimentary rock

• metamorphic rock

• intrusive igneous rock

• extrusive igneous rock

Has small or no crystals because of rapid cooling

• sedimentary

• metamorphic

• extrusive igneous

• intrusive igneous

If an igneous rock cools off slowly UNDERNEATH the Earth's surface, then its mineral crystals will be...

• Small mineral crystals that you can barely see.

• Large crystals that are easy to see.

• No crystals, it will have bits of plant and bones.

• No crystals, it will contain sand. 

Sedimentary rocks can have layers of different colors. This occurs when –

• molten rock seeps into large cracks underground.

• extreme pressure causes minerals to separate

• different minerals are deposited at different times.

• seasonal patterns change the rate of erosion.

Which of the following is one of the final processes in the formation of sedimentary rock?

• Melting

• Cementation

• Flowing

• Separation

Metamorphic rock forms where any kind of rock –

• is crystalized after being liquid rock.

• contains fossils of marine organisms

• is changed by the extreme heat and pressure.

• is composed of cemented sediment.
