1. Todays Goals Review Rock Cycle Review Plate Tectonics
Describe the rock cycle
Know the three types of rocks and how they are formed
Review Plate Tectonics
Be able to explain why tectonic plates move and describe some evidence for this

3. Type of Rock Igneous Rock
Form when magma hardens beneath the Earth’s surface
Granite is a type of igneous rock

4. Type of Rock Sedimentary Rock Do not form from pressure and heat
They form when minerals or organic particles settle and accumulate in rivers, streams and oceans
This is known as sedimentation
Sandstone is a type of sedimentary rock

5. Type of Rock Metamorphic rock
Metamorphic rocks are rocks that have "morphed" into another kind of rock. They were once igneous or sedimentary rocks.
How does this change occur?
The rocks are under tons and tons of pressure, which fosters heat build up, and this causes them to change.
Marble is a type of metamorphic rock
