7. What is a Sedimentary Rock? Formed by sedimentation of earth’s surface Bryce Canyon National Park Red Canyon, Utah
8. Sandstone Limestone Shale Conglomerate Gypsum Examples of Sedimentary Rocks Sandstone Rock Shale Rock
9. How are Igneous Rocks formed? Process 1 Formed underground Formed from melted rock(magma) Magma trapped in small pockets Magma cools down
10. Process 2 Formed above ground Volcanoes erupt Magma flows above ground As known as lava Lava cools down Igneous Formation Continued
11. How are Metamorphic Rocks formed? Once “igneous” or “sedimentary” Rock under large amount of pressure Heat builds up This is what morphs(changes) them
12. How are Sedimentary Rocks formed? Pieces of the earth breaks down Wash downstream Sit at bottom of the waters Repeats process to form layers Layers form pressure over time Pressure forms the sedimentary rock
13. The Rock Igneous Rocks Melting Heat/Pressure Weathering/ Erosion Melting Cycle Sedimentary Rocks Metamorphic Rocks Heat/Pressure Weathering/Erosion
14. What rock is formed from… Solidification of magma? Large amounts of pressure or heat? Pieces of the earth breaking down? Quiz
15. Igneous-From cooled magma/lave Can be above or below ground Metamorphic-From pressure/heat on rocks Once an igneous/sedimentary rock Sedimentary-From pressure on layers Pieces of the earth breaking down Summary
