| Question | Answer |
|---|---|
| Weathering | The mechanical breakdown of rocks without changing their chemical composition |
| Physical weathering | The scraping or wearing away of rocks by friction from other rocks, wind, or water. |
| Abrasion | The breakdown of rocks caused by chemical reactions, changing their mineral composition. |
| Chemical weathering | A type of chemical weathering in which oxygen reacts with minerals, often producing rust in iron-rich rocks. |
| Oxidation | Rain, snow, or fog that is more acidic than normal, speeding up chemical weathering. |
| Acid precipitation | The movement of sediments or rocks from one location to another by water, wind, ice, or gravity. |
| Erosion | The laying down of sediments in a new location after being transported. |
| Floodplain | The flat area of land next to a river that floods when the river overflows |
| Delta | A triangular deposit of sediments formed where a river meets a larger body |
| Alluvial fan | A fan-shaped deposit of sediments formed where a fast-flowing stream slows down upon reaching flatter land |
| Groundwater | Water that saturates soil and rock beneath the Earth’s surface. |
| Shoreline | The boundary where land meets a body of water. |
| Beach | An area of loose sediment along a shoreline, often sand or pebbles. Sandba |
| Sandbar | A submerged or partially exposed ridge of sand built up by water current |
| Barrier island | A long, narrow island parallel to the coast, protecting the mainland from waves and storms. |
| Dune | A hill or ridge of sand formed by wind deposition. |
| Loess | fine silt or clay deposited by wind, often creating fertile soil. |
| Glacier | A large, slow-moving mass of ice formed from compacted snow. |
| Glacial drift | Sediment deposited by a glacier. |
| Creep | The slow downhill movement of soil or rock due to gravity. |
| Rockfall | The rapid downward movement of rocks from a steep slope. |
| Landslide | The sudden movement of soil, rock, or debris down a slope. |
| Mudflow | A rapid flow of water-saturated soil and debris down a slope, often following heavy rain. |
| Mountain | A landform that rises prominently above its surroundings, usually with steep slopes. |
| Lake | A body of water surrounded by land. |
| River | A natural flowing body of water that moves toward another water body. |
| Coastline | The outline of a coast where land meets the ocean or sea. |
