| Abrasion | The physical action of scraping, rubbing, grinding, or wearing away of rock surfaces and sediments due to the movement of solid sediments in an erosional system such as a stream or wind |
| Breaking Wave | The result of waves dragging on the ocean bottom causing the water in the waves to fall forward as the waves bunch together, rise up, and break against the shore |
| Chemical weathering | The process by which chemicals, such as oxygen, acids, and water break down rocks and other earth materials, resulting in more stable new materials |
| Delta | The deposit of sediment at the mouth or end of a river or stream where it flows into a quiet body of water such as a lake or ocean |
| Erosion | The carrying away of sediment by wind, water, ice, and other agents |
| Finger Lake | A body of water that forms in a long, narrow U-shaped glacial valley |
| Flood Plain | A nearly level plain that borders a stream that is subject th flooding unless protected artificially |
| Glacial Groove | A long narrow channel or furrow on bedrock formed by the gouging and sanding actions of rocks and sediments frozen to the bottom of a glacier |
| Glacial Parallel Scratches | Parallel cuts in bedrock formed by abrasion of rocks and sediments frozen to the bottom of a glacier |
| Glacier | A large mass of naturally formed ice on land that moves downhill due to gravity |
| Mass Movement | Any variety of erosion and deposition done directly by gravity |
| Meander | A curve or bend in a stream or river |
| Physical weathering | The mechanical or physical breakdown of rock and other earth's materials at or near earth's surface into smaller pieces without a change in the mineral or chemical compostition |
| Sandbar | A pile or low ridge of sand, often just above or just below water level, deposited by waves and current |
| Sandblasting | An erosional process by which blowing sand impacts and abrades rock surfaces resulting in shaped landscape features and new sediments |
| Sediment | Particles or materials formed by the weathering and erosion of rocks or organic materials |
| Stream | water flowing through a channel on land |
| Stream abrasion | The rounding, smoothing, and size reduction of sediments resulting from the rolling, sliding, or bouncing of large solid sediments along a stream bottom |
| Stream channel Shape | The shape of the body of rock or loose materials that confine the stream |
| Tributary | Small stream or river that flow into a larger stream or river |
| U-shaped Valley | The characteristic shape of a valley after it has been eroded by glaciers, especially mountain glaciers, as compared to the V-shaped valley eroded by streams |
| V-shaped Valley | The characteristic shape of a valley eroded by a stream or river, as compared to a U-shaped glacial valley |
| Watershed | The area of land drained by any one stream |
| Weathering | The chemical and physical alterations of rock and other earth's materials at or near earth's surface through the action of temperature changes, water, chemical agents, atmospheric gases, and organic materials |
