Powerpoint project final

  1. 1. By: Catie McGee<br />Changes in the earth’s surface<br />
  2. 2. Erosion<br />Glaciers<br />Volcanoes<br />Earthquakes<br />Landslides<br />Natural causes of change<br />
  3. 3. The Process that breaks things down. <br />Erosion<br />
  4. 4. After it rains and you go outside to play, you might notice a lot of small rocks and dirt at the bottom of a hill. <br />This is because erosion took place. <br />The water washed the smaller material down the hill. <br />example<br />
  5. 5. The processes that change the character of rocks at or near the Earth's surface<br />Weathering<br />
  6. 6. Mechanical Weathering<br />Physical<br />Breaks down rocks into smaller pieces<br />Caused by water freezing and melting<br /><ul><li>Usually at the Earth’s surface</li></ul>First type<br />
  7. 7. Chemical Weathering<br />Rock Decomposition<br />Rocks are exposed to water and gases <br />Change chemical compounds- form new rocks<br />Second type<br />
  8. 8. A large river of ice that moves very slowly. <br />glaciers<br />
  9. 9. While glaciers move slowly, they carve out the ground. <br />The carving makes valleys. <br />Making of valleys<br />
  10. 10. A mountain that opens down into a pool of molten rock below Earth’s surface. <br />volcanoes<br />
  11. 11. Plates under Earth’s crust move apart<br />Movement causes friction<br />Friction causes pressure build up<br />High pressure causes a volcanic eruption<br />How they work…<br />

  13. 13. Shaking at the surface of the Earth because of movement underground along a fault line/volcanic activity. <br />earthquakes<br />
  14. 14. Determines size of an earthquake<br />Uses seismic waves<br />- A wave that travels through the Earth<br />Richter magnitude scale<br />
  15. 15. 2.9 and lower Not felt<br />3.0-4.9<br />Felt but little damage<br />5.0-10<br />Felt and a lot of damage<br />Richter magnitude scale<br />
  16. 16. Rocks and other material sliding down a mountain or cliff.<br />landslides<br />
  17. 17. Rain- adds weight <br />Erosion- base is removed<br />Earthquakes- loosens material<br />Volcanic eruption- flowing lava<br />Humans:<br />Mining<br />Deforestation <br />causes<br />
