1. The Rock Cycle Thinking about relationships among the major rock groups

2. 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.

3. Rock Types Igneous Basalt, Pumice and Obsidian, Granite Sedimentary Chalk, Shale, Travertine, Flint and Coal 3

4. Rock Types Metamorphic Marble, Slate and Soapstone 4
