Episode 12: Glaciers

Send us Fan Mail In this episode of the podcast, I have talked about Glaciers and its classification along with distribution and Also talked about my questions that I asked my professor at my university. How Do Glaciers Move? How do glaciers move? How Fast Do Glaciers Move? Additional Information Arêtes are narrow, serrated, knife-edge ridges forming a thin partition between two cirques or adjacent parallel glacial troughs. Horns are pyramidal, steep-walled mountain peaks formed by headward erosion of cirques. To form, a horn must have at least three cirques on its flanks. Glacial Deposits: Both valley and continental glaciers deposit their sediment load as glacial drift, a general term for glacially deposited material. A vast sheet of the glacial drift of the Pleistocene Epoch blankets the northern U.S. and adjacent Canada. Erratics are boulders eroded and transported by glaciers and deposited in areas from which they were obviously not derived. Till is poorly sorted sediment deposited by glacial ice. Stratified drift is layered, sorted sediment deposited by flowing meltwater. Morraines The outermost end moraines deposited when the glacier was at it greatest extent are called terminal moraines. If the glacier recedes and eventually stabilizes at a new location, an end moraine has known as a recessional moraine accumulates at the terminus. Ground moraines are deposited as glaciers recede and sediment is liberated form the melting ice. Ground moraines have an irregular, rolling topography.
