GEOL 1001 : Geology Midterm 2
Document Summary
Transport of sediment is usually intermittent: deposition occurs when wind and water currents slow down and as glacial ice melts. Accumulation of sediments and laying them down; usually after being moved by wind, water, or ice. Not related to the strength of wind or water currents. Water melting from glaciers transport and redeposit some sediment creating stratified, sorted accumulations: eolian the work of wind and its resulting deposits. Well-sorted, can lift fine dust high into the atmosphere and transport it great distances: dunes sand is transported close to the ground, where it accumulates in dunes. Deserts and coasts are common sites for this type of deposition: marine depositional environments are divided according to the depth, shallow marine reaches depths about 200 meters and borders all of the world"s continents. Receives huge quantities of land-derived sediment: deep marine seaward of the continental shelf in waters deeper than 200 meters (all floors of the deep ocean).
