WebFinal answer. Step 1/3. Glaciers are one of the most powerful forces of nature and have a profound impact on the landscapes they shape. As glaciers move across the earth's surface, they can carve out deep channels and potholes in the bedrock beneath them. Understanding the forces behind this process is essential for geologists, environmental ... WebThe long profiles of proglacial rivers and outwash surfaces are concave upward as a consequence of persistent aggradation. Where proglacial rivers enter standing water bodies, classical, high-angle deltas develop. Sediment transported as bed load is deposited on the delta surface, or is deposited on the foreset wedge by avalanching over the ...

After emerging from its ice tunnel a meltwater stream spreads out and slows down, depositing debris. The channels become choked and the stream has to find new routes, which may result in a braided stream with channels separated by bars of gravel or sand.
