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