• Sandstone

• Granite

Minerals have a definite chemical composition, are inorganic, solid and crystalline, and occur naturally.

• True

• False

A metamorphic rock forms from

• High heat pressure and any rock

• extreme tempuratures and any rock

• a igneous rock with another metamorphic rock in a volcano

• Extreme heat, pressure and sedimentary rock

What are the two types of metamorphism

• Volcanic

• Contact

• Regional

• Radiaton

What is banding?

• extreme foliation when minerals separate into stripes of color

• foliation when a sedimentary rock is formed nearby

Is the rock cycle the process where any rock can change into any other type of rock

• True

• False

igneous rock weathers and erodes, rock particles are lost forever Then sand gets molded by hot radiation and becomes sedimentary. The sedimentary rock falls into a volcano and becomes metamorphic.

• This is the process of the rock cycle

• This is not the process of the rock cycle

• This is not even related to the rock cycle
