Erosion:
* Process: The wearing away and transportation of Earth materials (rock, soil, sediment) by natural forces like wind, water, ice, and gravity.
* Direction: Movement of material *away* from its original location.
* Examples:
* Rivers carving canyons
* Wind creating sand dunes
* Glaciers scouring valleys
* Waves eroding coastlines
Deposition:
* Process: The dropping or settling of eroded material in a new location.
* Direction: Movement of material *towards* a new location.
* Examples:
* Rivers forming deltas at their mouths
* Wind creating loess deposits
* Glaciers leaving moraines
* Waves depositing sand on beaches
Key Differences:
* Direction of material movement: Erosion is about *removal* of material, while deposition is about *adding* material.
* Result: Erosion creates features like valleys, canyons, and beaches, while deposition creates features like deltas, dunes, and moraines.
Think of it like this: Erosion is like a sculptor carving away at a piece of marble, while deposition is like adding clay to a sculpture to build it up. Both are essential for shaping the landscape, working together in a dynamic cycle.
