The document discusses the three main types of rocks - igneous, metamorphic, and sedimentary rocks - and how they are formed through the rock cycle. Igneous rocks form from the cooling of magma or lava. Metamorphic rocks form from existing igneous or sedimentary rocks through heat, pressure, and strain in the Earth. Sedimentary rocks form through the lithification of sediment derived from the weathering and erosion of other rocks. The rock cycle describes how rocks continuously transform between these three types through geological processes over long periods of time.

2. The Rock Cycle Three Types of Rock Cooling Igneous Magma/ Lava Heat/ Pressure Erosion/ Lithification Erosion/ Lithification Metamorphic Sedimentary Heat/ Pressure
3. Igneous Rock Formed two ways Underground Intrusive (or Plutonic) Cooling magma chambers Above ground Extrusive (or Volcanic) Cooling lava
4. Igneous Rock Cooling Rates Rapid cooling Fine texture No visible crystals Sometimes glassy Sometimes full of air pockets Slow cooling Coarse texture Large crystalsvisible
5. Igneous Rock Mafic Rock Rich in magnesium (Mg) and iron (Fe) Felsic Rock Rich in feldspar and silica (quartz)
7. Metamorphic Rock Formed from Igneous and Sedimentary rock Changed by underground conditions (metamorphosed) Heat, pressure, and strain
8. Metamorphic Rock Regional Metamorphism Large-scale Heat and pressure work together 5- 40 km underground Contact Metamorphism Lava or magma in contact with rock Dynamic Metamorphism Pressure along fault zones Mylonites
9. Metamorphic Rock Foliated- Orientation of minerals is perpendicular to direction of pressure. Non-foliated- No preferred orientation.
10. Sedimentary Rock Formed from sediment Sediment- sand, pebbles, mud, dust… How is sediment created? Erosion- weathering of rock causes material to break off
