1.3: Erosion and Deposition

  1. Erosion: The process by which sediment and other materials are moved from one place to another
    1. Forms of Erosion
      1. Canyons & Valleys: When a flow of water through streams and rivers erode rock from the streambed
      2. Caves: Water erodes the rock, eventually forming a cave
      3. Sea Cliffs: When waves erode and undercut rock to make steep slopes
      4. Wave cut platforms: When sea cliffs erode so much that the they are flat
      5. Sea Caves: When the bottom of sea cliffs erode faster than the top
      6. Sea Arches: When a sea cave erodes all the way to the other side, forming a hole
      7. Sea stacks: When a sea arch collapses, it leaves behind pillars of rock
  2. Deposition: The process by which eroded material is dropped
    1. Forms of Deposition
      1. Floodplains: When sediment is dropped over a flooded land
      2. Deltas: Streams deposit sediment in a fan-shaped pattern
      3. Alluvial Fan: A dry fan-shaped pattern of sediment
      4. Beaches: Particles can come up on a beach
