• Erosion - the removal of ground materials (soil, sand, rocks) by water or wind.
Taking rocks, soil, and/or sand from one place…
… and depositing them somewhere else.

Glacier Example: Iceland
- Glaciers are very powerful.
- They carve out huge chunks of land forming canyons and valleys thus creating mountains out of flat land.

2. Wind Erosion - wind blows sand and small particles
- This exposes the larger rocks below and smoothes them down.
