  1. Rock Cycle

  2. Elements Around Us Earth’s ATMOSPHERE

  3. Elements Around Us Earth’s OCEANS

  4. Elements Around Us Earth’s CRUST

  5. IGNEOUS ROCKS • Forms from cooled lava. • Most have crystals… the size of the crystal depends on how fast the lava cooled. - Slow cooling = large crystals - Fast cooling = small to microscopic • Some rocks have pores (like a sponge) from the gases in the lava escaping during the cooling process.

  6. IGNEOUS ROCKS Granite Obsidian Pumice Gabbro

  7. SEDIMENTARY ROCKS Sediments that have deposited will be compacted and cemented together. Formed from weathered igneous, sedimentary, and metamorphic rocks… that’s where the sediment comes from!!! • Usually layers can be seen. • Some are conglomerates… i.e. you can see smaller rocks or shells embedded.

  8. SEDIMENTARY ROCKS Conglomerate Shale Limestone Banded-Sandstone

  9. METAMORPHIC ROCKS Formed deep within the Earth’s crust… rocks that undergo an extreme amount of heat and pressure.
