1. Rock Cycle 1

2. Igneous Rock Formed when magma cools Inside the Earth Above the ground
Can be heated under pressure
Becomes metamorphic rock
Can be melted again to form new magma
Above the ground
Can be weathered and eroded
Becomes sedimentary rock

3. Igneous Rock Continued…
Intrusive – Large grained
Cools below the surface of the Earth
Large crystals form when magma cools very slowly
Extrusive – Fine grained
Cools close to surface or above the ground
Small crystals form when magma cools rapidly

4. Igneous Rock Continued…
Vesicular – describes an igneous rock that has holes due to the formation of bubbles when gas is escaping during cooling

5. Sedimentary Rock Formed when sediments compact & cement into layers
Inside the Earth
Can be heated under pressure to form metamorphic rock
Above the ground
Can be weathered again to form more new sediment

6. Metamorphic Rock Formed when rock changes under heat & pressure
Inside the Earth
May melt to form magma
Above the ground
May weather & erode to form sediment

7. Metamorphic Rock Continued…
Foliation – banding of mineral concentrations in metamorphic rocks. Has the appearance of stripes or lines in the rock.
