| Sediment | Small, solid pieces of materials that comes from rocks or the remains of organisms; earth materials deposited by erosion. |
| Deposition | Process in which sediment is laid down in new locations. |
| Gravity | The attractive force between objects; the force that moves objects downhill. |
| Mass Movement | Any one of several processes by which gravity moves sediment downhill. |
| Runoff | Water that flows over the ground surface rather than soaking into the ground. |
| Rill | A tiny groove in soil made by flowering. |
| Gully | A large channel in soil that carries runoff after a rainstorm. |
| Stream | A channel through which water is continually flowing downhill. |
| Tributary | A stream or river that flows into a larger river. |
| Flood Plain | The flat, wide area of land along a river. |
| Meander | A loop like bend in the course of a river. |
| Oxbow Lake | A meander cut off from a river. |
| Delta | A landform made of sediment that is deposited where a river flows into a lake or ocean. |
| Alluvial Fan | A wide, sloping deposit of sediment formed where a stream leaves a mountain range. |
| Groundwater | Water that fills the cracks and spaces in underground soil and rock layers. |
| Stalactite | An icicle like structure that hangs from the ceiling of a cavern. |
| Stalagmite | A column like forms that grow upward from the floor of a cavern. |
| Karst Topography | A region in which a layer of limestone close to the surface creates deep valleys, caverns, and sinkholes. |
| Glacier | Any large mass of ice that moves slowly over land. |
| Continental Glacier | A glacier that covers much of a continent or large island. |
| Ice Age | Time in earth's history during which glaciers covered large parts of the surface. |
| Valley Glacier | A long, narrow glacier that forms when snow and ice build up in a mountain valley. |
| Plucking | The process by which a glacier picks up rocks as it flows over the land. |
| Till | The sediments deposited directly by a glacier. |
| Moraine | A ridge formed by the till deposited at the edge of a glacier. |
| Kettle | A small depression that forms when a chunk of ice is left in glacier till. |
| Headland | A part of the shore that sticks out to the ocean. |
| Beach | Wave-washed sediment along a coast. |
| Longshore Drift | The movement of water and sediment down a beach caused by waves coming in to shore at an angle. |
| Spit | A beach formed by longshore drift that projects like a finger out into the water. |
| Deflation | The process by which wind removes surface materials. |
| Sand Dune | A deposit of wind-blown sand. |
