What is a fossil?
100
A continuous process by which rocks are created, changed from one form to another, destroyed, and then formed again.
What is the rock cycle?
200
The two processes that change Igneous Rocks and Sedimentary Rocks into Metamorphic Rock.
What is heat and pressure?
200
The type of rock that is formed by metamorphic rock melting into magma then cooling.
What is Igneous Rock?
200
The science of determining the relative order or past events, without necessarily determining their absolute age.
What is relative dating?
200
A rock that was swept into a volcano then cooled and hardened from magma.
What is Igneous Rock?

The process that changes sediments into Sedimentary Rock.
What is compacting and cementation?
