|---|
| WEATHERING | breaking apart rocks or minerals (occurs faster in hot wet climates) |
| EROSION | movement of weathered material |
| DEPOSITION | the dropping off of weathered material in a new location |
| SLUMP | a large mass of material slips down a curved surface |
| CREEP | sediments slowly shifting down hill |
| ROCK FALLS | blocks of rock break loose from a steep slope and tumble through the air |
| SCOURING | as glaciers move down hill rock and sediments frozen to the bottom of the glacier scrape the soil and bedrock like sandpaper |
| DEFLATION | a type of erosion that occurs when wind blows over loose sediments and removes small particles, and leaves heavier sediments behind |
| ABRASION | a type of erosion that occurs when windblown sediments strike and wear away the rocks, similar to sandblasting by leaving a smooth surface |
| SAND/DUST STORMS | sand and dust blown up into the air, causing obscure visibility; normally occurs in dry regions |
| ROCK SLIDES | layers of rock suddenly slip down hill |
| DOWN SLOPE | bottom slanted portion of a hill or mountain |
| MORAINE | large ridge of rocks and soil deposited by a glacier when it stops moving |
| OUTWASH | material deposited by meltwater from a glacier |
| ESKER | deposits along a winding ridge formed when a glacier starts to melt and forms a river within the ice |
| LOESS | fine grained windblown sediments that have been deposited on hilltops and valleys that are now tightly packed together |
| DUNES | mound formed when windblown sediments pile up behind an obstacle; common landform in desert areas |
| MUDFLOWS | thick mixture of water and sediments flowing downhill |
| PLUCKING | process that adds gravel, sand, and boulders to the sides and bottom of a glacier as they thaw and then refreeze |
