Presentation Transcript

  1. The Rock Cycle

  2. Rocks • Rock- mixture of minerals, glass, or organic matter compacted together • examples: granite, limestone, obsidian

  3. Minerals • Mineral- naturally occuring, non-living solid composed of elements or compounds • examples: quartz, pyrite, garnet

  4. Rock Cycle • The rock cycle shows how rocks are formed and changed from one form to another.

  5. Heat & Pressure = Metamorphic Rock • Melting & Cooling = Igneous Rock • Weathering & Erosion = Sediment • Compaction & Cementation = Sedimentary Rock

  6. Types of Rocks • There are 3 types of rocks formed on Earth: • Igneous, Metamorphic, and Sedimentary

  7. Igneous Rocks • Igneous rocks are formed when molten rock material (magma) is melted deep inside Earth and cooled as it rises toward the surface of the Earth as lava. • 1. Intrusive igneous rocks- rocks that form below Earth’s surface, cools slowly so large crystals are able to form • 2. Extrusive igneous rocks- rocks that form near or on Earth’s surface, cools quickly so no large crystals form

  8. Igneous rocks can also be classified by magma type • Basaltic rocks are dense, heavy, dark-colored rocks formed by basaltic magma. • Rich in iron and magnesium • Granitic rocks are light colored, less dense, thick, and stiff • Rich in silicon and oxygen • Creates violent eruptions • Discover How Rocks Are Formed
