7. What is a Metamorphic Rock? Metamorphism- Change effected by heat/pressure Produced by metamorphism Creigh Hill, Scotland
8. How are Metamorphic Rocks formed? Once “igneous” or “sedimentary” Rock under large amount of pressure Heat builds up This is what morphs(changes) them
10. What is a Sedimentary Rock? Formed by sedimentation of earth’s surface Bryce Canyon National Park Red Canyon, Utah
11. How are Sedimentary Rocks formed? Weathering Deposition Erosion Lithification Compaction
12. Sandstone Limestone Shale Conglomerate Gypsum Examples of Sedimentary Rocks Sandstone Rock Shale 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? Weathering and erosion? 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 weathering and erosion Pieces of the earth breaking down Summary
