The Rock Cycle Thinking about relationships among the major rock groups
2 Major Rock Groups Igneous –Formed from a melt (molten rock) –Plutonic (intrusive):slow cooling and crystallization –Volcanic (extrusion): quick cooling at the surface Sedimentary –Formed at the Earth’s surface –Clastic (Mineral Fragments or grains, clays) –Chemical (crystalline chemical/biochemical precipitates) Metamorphic –Changed by pressure, temperature and fluids.
Rock Types Igneous Basalt, Pumice and Obsidian, Granite Sedimentary Chalk, Shale, Travertine, Flint and Coal 3
Rock Types Metamorphic Marble, Slate and Soapstone 4

7 MAGMA IGNEOUS Plutonic Crystallization
8 MAGMA Volcanic IGNEOUS Plutonic Crystallization
9 MAGMA Volcanic IGNEOUS Plutonic Uplift Crystallization Weathering Erosion
10 MAGMA Volcanic IGNEOUS Plutonic SEDIMENT Uplift Crystallization Weathering SEDIMENT
11 MAGMA Volcanic IGNEOUS Plutonic SEDIMENT SEDIMENTARY Uplift Crystallization Weathering Erosion Transport Deposition
12 MAGMA Volcanic IGNEOUS Plutonic SEDIMENT SEDIMENTARY Uplift Crystallization Weathering Erosion Transport Deposition
13 MAGMA Volcanic IGNEOUS Plutonic SEDIMENT SEDIMENTARY METAMORPHIC Uplift Burial Increased P&T Crystallization Weathering Erosion Transport Deposition
14 MAGMA Volcanic IGNEOUS Plutonic SEDIMENT SEDIMENTARY METAMORPHIC Uplift Burial Increased P&T Melting Crystallization Weathering Erosion Transport Deposition Can you see any shortcuts?
