GeographyglaciationASOCR Created by: aminaamriCreated on: 12-05-17 21:34 42635791081 Across 1. 3 or more corries creating a pyramid at the top (4, 2, 1, 9, 4) 4. Distinct layers of slit lying on top of a lyaer of sand, deposited annually, found near glacial margins. (4, 2, 1, 5) 5. Mounds of sediment that consist of sand & gravel that has built up into a mound. As the glacier melts, more sediment is deposited on top of the old debris. Unsupported kames tend to collapse & leave a mound. (4, 2, 1, 4) Down 2. Temperatures under 0 degrees, snow compacts into firn. The weight of the firn adds pressure and meltwater causes rotational slip to occur. Plucking then occurs on the back wall. (3, 2, 1, 6, 6) 3. Includes all losses of ice from a glacier, including meltwater, evaporation, sublimation & iceberg carving (4, 2, 8) 6. Large plateaus of ice on high land (4, 2, 2, 3, 3) 7. When meltwater seeps into the joints in the rock of valley sides/ floor. This freezes and joins to the glacier. As the glacier advances it pulls pieces out with it. (4, 2, 8) 8. Small glaciers on upland slopes (4, 2, 1, 5) 9. Round ice covered hills. Can be open system or closed system. (4, 2, 1, 5) 10. Due to steeping or undercutting valley. Slides can be rotational. (4, 3, 6)
