GEOL 1304 Lecture Notes - Lecture 6: Cirque Glacier, Percy Snow, U-Shaped Valley
Document Summary
Ice fields longer comic strip of meth . elongated patter in mountainous area. The process by which the bottom most bed of a glacier is pressure level melted, creating a fender stratum of water to move the glacier faster. Speed depends on the gradient of the landform, the temperature and thickness of the shabu , and the width of the valley it"s moving in. Accretion (from incoming snow) vs ablation (melting, cutting at the close , sublimation , and erosion by wind). Zones of accumulation and ablation are divided by the rn limit. cwm depression basin in a valley formed by glacial erosion and frost wedging. Cirque glaciers are formed in here by charles percy snow collapse of the snow above it. Cirque glacier snow builds up in a depressed drainage basin called a corrie former glaciated valley meets the sea , and can be carved even deeper than sea level. Arete the "knife edged", serrated ridges that offprint valleys.
