What processes change Earth’s surface?

  1. 1. Weathering: Weathering is the process of breaking down rock into small pieces of silt, sand, and clay known as sediments.
  2. 2. Weathering: the process of breaking rock into silt, sand, clay, and other tiny pieces called sediment Rivers carve deep canyons in rock. Just like Arizona’s Grand Canyon!
  3. 3. Weathering: the process of breaking rock into silt, sand, clay, and other tiny pieces called sediment Ocean waves can weather cliffs and cause them to fall into the sea!
  4. 4. Weathering: the process of breaking rock into silt, sand, clay, and other tiny pieces called sediment Rain that flows into cracks in rocks can freeze and expand, causing the rock to break!
  5. 5. Weathering: the process of breaking rock into silt, sand, clay, and other tiny pieces called sediment Rain that becomes acidic because of pollution can dissolve rock!
  6. 6. Weathering: the process of breaking rock into silt, sand, clay, and other tiny pieces called sediment Flowing water tumbles rocks against each other, breaking them into smaller pieces.
  7. 7. Wind is another cause of weathering. These arches form from years of wind carrying sand! Weathering: the process of breaking rock into silt, sand, clay, and other tiny pieces called sediment
  8. 8. Erosion Erosion is the process of moving sediments from one location to another.
  9. 9. Erosion: the process of moving sediment from one place to another Waves erode and deposit new sand on beaches.
  10. 10. Erosion: the process of moving sediment from one place to another Rivers carry sediment and move it downstream.
  11. 11. Deposition Deposition is the process of dropping or depositing sediments in a new location.
  12. 12. Deposition: the process of dropping, or depositing, sediment in a new location Waves deposit sand on the shore and rivers deposit sediment on river banks or in deltas.
  13. 13. Erosion: the process of moving sediment from one place to another Wind also erodes land. It carries sand and sediment from one place to another.
  14. 14. Erosion: the process of moving sediment from one place to another Glaciers can also erode sediment and deposit it in another area. Deposition: the process of dropping, or depositing, sediment in a new location
  15. 15. Valley Glacier Continental Glacier
