Rocks and Minerals

Name ____________________

Explain why most fossils are found in sedimentary rock.

What is left of a once-living thing is buried by sediment and becomes part of the

sedimentary rock. Fossils DO NOT survive the heat and pressure required to make igneous

and metamorphic rock.

Can igneous rock change into metamorphic rock? Explain.

Yes, igneous can change into metamorphic rock when it is exposed to a lot of heat and

pressure.

Can an igneous rock sitting in our classroom become a metamorphic rock?

No, there is not enough heat and pressure in the classroom for the rock to change forms.

How can Bob make a model of a cast and mold for a science project?

He could take a shell and put Vaseline on it. Then he could push it into clay to make

impression. That is the mold of the shell. He could make a cast by filling the mold with glue

or plaster.
