weathering
| Question | Answer |
|---|---|
| weathering | the natural process of breaking down, dissolving, or decomposing rocks and minerals on the Earth’s surface into smaller pieces (sediments) due to exposure to air, water, ice, temperature changes, and biological activity |
| physical weathering | the process of breaking down rocks, minerals, and soils into smaller fragments without altering their chemical composition |
| abrasion | a superficial,, often painful injury where the top layer of skin (epidermis) is scraped, rubbed, or worn away by friction against a rough surface |
| chemical weathering | the breakdown of rocks, soils, and minerals through chemical reactions that alter their mineral composition, rather than just breaking them into smaller pieces |
| oxidation | any electron-loss process, typically paired with reduction in redox reactions |
| acid precipitation | any form of precipitation—rain, snow, fog, or dust—with unusually high levels of sulfuric and nitric acids, typically having a pH lower than 5.6 |
| erosion | the geological process where natural forces like water, wind, ice, or gravity wear away and transport soil, rock, or dissolved materials from one location to another |
| deposition | A deposition is a formal, out-of-court, sworn testimony given by a witness or party in a legal case, typically during the pre-trial discovery phase. |
| floodplain | a generally flat or low-lying area of land adjacent to a river, stream, or water body that experiences periodic inundation (flooding) when water overflows its banks |
| delta | Over Torque Detection |
| alluvial fan | a fan- or cone-shaped deposit of sediment (sand, gravel, boulders) created when a fast-flowing mountain stream or river suddenly slows down and spreads out upon reaching a flat valley floor or plain |
| groundwater | water located beneath the Earth's surface that fills the pore spaces in soil, sand, and rock, occurring in completely saturated zones |
| shoreline | the precise boundary line where a body of water (ocean, sea, lake, or river) meets the land |
| beach | a team has stopped working, lost focus, or is already thinking about a holiday |
| sandbar | a long, narrow submerged or partially exposed ridge of sand, gravel, or sediment built up in shallow water along a shore, in a river, or at a harbor mouth by the action of currents and waves |
| barrier island | a long, narrow, offshore deposit of sand and sediment running parallel to the coastline, separated from the mainland by a lagoon, marsh, or bay |
| dune | a mound, ridge, or hill of loose sand piled up by the wind, commonly found in deserts or along coastlines |
| loess | a fine usually yellowish brown soil found in North America, Europe, and Asia and believed to be chiefly deposited by the wind |
| glacier | |
| glacial drift | |
| creep | |
| rockfall | |
| landslide | |
| mudflow | |
| mountain | |
| lake | |
| river | |
