What are the two types of fossils?
A mold, and a cast. A mold is what's left after the plant or animal decays; the empty space left in the rock.

How are metamorphic rocks made?
Metamorphic rocks are made by heat and pressure. They change form, or go through a metamorphosis.
200
How are minerals grouped? By the way they are formed or by how they look?
They are grouped by the way they are formed.

What is an imprint fossil?

400
Name something other than a rock or mineral that you liked learning about.
What is a fossil or sea glass, or other appropriate answer.

Describe the rock cycle.
Igneous rocks form underground from molten magma. If they stay underground they would turn to metamorphic because of heat and pressure. If the igneous rock came out of the volcano, it would wear away over time, forming sediments, turning into sedimentary rock. This process takes 1,000's of years.
500
Is volcanic a type of rock?
No, the types of rocks are igneous, sedimentary, and metamorphic.
