| Erosion | movement of sediment |
| Deposition | Dropping of sediments |
| Mass movement | erosion that occurs as gravity moves a lot of material down-slope |
| slump | A type of mass movement that occurs when mass of material moves down a curved slope |
| creep | A type of mass movement in which sediments move down-slope very slowly; is common in areas of freezing and thawing, and cause walls, trees, and fences to lean downhill |
| glacier | Large, moving masses of ice and snow that change large areas of Earth's surface through erosion and deposition |
| iceberg | Huge ice formation from the breaking of ice shelves at poles of earth - floats in ocean and most is below surface |
| plucking | Process that adds gravel, sand, and boulders to a glacier's bottom and sides as water freezes and thaws, breaking off pieces of surrounding rock |
| till | Mixture of different sized sediments that is dropped from the base of a retreating glacier and can cover huge area of land |
| moraine | Large ridge of rocks and soil deposited by a glacier when it stops moving forward |
| outwash | Material deposited by the meltwater from a glacier, most often beyond the end of the glacier |
| deflation | erosion that occurs when wind blows across loose sediment removes small particles and leaves coarser sediment behind |
| abrasion | erosion that occurs when windblown sediments strike rocks and sediments, polishing and pitting their surface |
| loess | Windblown deposit of tightly packed, fine-grained sediments |
| dune | Mound formed when windblown sediments pile up behind an obstacle; common landform in desert areas |
| arete | ridge line formed when a glacier moves on both sides eroding soil and rock away |
| horn | land formation due to glaciers weathering and eroding soil and rock away on several sides of a mountain |
| u-shaped valley | land formation left after a glacier moves through mountains |
| v-shaped valley | land formation due to flowing of water weathering and eroding soil and rock away |
| erosion | wearing away surface materials and moving them to another location |
| deposition | process of dropping sediments when the energy of motion decreases |
| creep | sediments slowly inch down a hill |
| creep | erosion of sediment that causes fences to lean |
| moraine | glacial deposit that looks like it's been pushed into place by a bulldozer |
| glacier | ice and snow moving under its own weight |
| abrasion | process of wind-blown sediments scratching and scraping rock |
| slump | a mass movement that occurs when materials slip down a curved slope |
| loess | fine-grained sediments deposited by the wind |
| plucking | boulders, gravel, and sand being added to the bottom of a glacier |
| till | glacial deposits that can completely fill valleys |
| deflation | process of wind removing small particles |
| mass movement | erosion that happens as gravity moves materials downslope |
| outwash | material deposited by the meltwater from a glacier |
| dune | a mound of sediments drifted by the wind |
