1. Rock Cycle

2. Rocks
Naturally formed
Solid
Mix of minerals and/or organic matter

3. What is the Rock Cycle? Continual process
New rocks form from old rock material
No beginning or end (each type can turn into each of the three types)

4. Types of Rocks
Igneous
Sedimentary
Metamorphic

5. How are igneous rocks formed?
Rock pieces melt into magma
Magma cools to form intrusive igneous rock
Lava cools to form extrusive igneous rock

6. How are Sedimentary Rocks formed?
W.E.D.C. forms a sedimentary rock.
Weathering  Erosion  Deposition  Compaction/Cementation
Weathering- water, wind, ice, heat break down rock
Erosion- sediment is transported from one location to another
Deposition- sediment moved by erosion settles in bodies of water or low-lying areas
Compaction- sediments squeeze together to form a rock

7. How are metamorphic rocks formed?
Intense heat and pressure
