1. Rock Cycle

2. Rock Cycle Info
A diagram showing the relationship among the three major rock groups
(sedimentary, metamorphic, igneous)
Powered by:
Convection Currents
Interior heat of the Earth - magma
Energy from sun
Wind
weathering and erosion

3. Sediments------- 3. Sedimentary Rocks
1. Compaction/cementation
sediments accumulate at the surface of the Earth or on ocean floor
Hardening of rock fragments by adding in mineral “glue”

4. 2. Weathering, erosion, deposition
Breaking down of rocks through contact of Earth’s atmosphere
Erosion
Moving of solids by current – wind/water
Deposition
Deposit on Earth’s surface or water

5. Sedimentary Rock ----- 5. Metamorphic Rock
4. Heat and Pressure
Bonds between minerals are rearranged due to heat and pressure (recrystallization)
Existing rock is altered

6. 6. Melting:
Sink deeper into hot mantle and melt
Depends on:
A. presence of fluids
B. Pressure
C. Temp

7. Magma / Lava----- 12. Igneous rock
7. Melting
8. Solidification
Underground or above ground
volcanoes
Magma cools
9 and 11. weathering/erosion/deposition
10. heat and pressure (recrystallization)
