|---|---|
| gradual breakdown of rock into smaller pieces by natural process | Weathering |
| breaks rocks apart into smaller and smaller pieces that retain the characteristics of the original rock | Physical Weathering |
| the process that changes the composition of rock, forming new minerals that have properties different from those of the original rock | Chemical weathering |
| a process when tiny rock fragments carried by wind and water wear down platforms | abrasion |
| the wearing away of Earth's surface by the breakdown and transportation of rock and soil | erosion |
| the process by which the eroded soil and rock are put down in new places, reshaping the landscape | deposition |
| mounds formed in the desert or on beaches from particles of sand that have been deposited by the wind | sand dunes |
| weathered rock particles | sediment |

| a portion of a stream channel that is cut off from the rest of the stream by erosion | oxbow lake |
| a fan shaped land deposit at the mouth of the stream | alluvial deposits |
| the process by which waves pick up sand particles and move along the shore | beach erosion |
| a flat step of rock formed in an exposed, windy area where the waves pound hard against the shore | marine terrace |
