What are two typyes of glacial deposits?
Two types of glacial deposits are moraines, which are formations of mixed sediment pushed by and deposited from a glacier, and drumlins, which are elongated hills made of glacial till that form parallel to the direction of ice flow.
What is a narrow bay formed by tectonic process and later modified by glacial action?
A fjord is a narrow bay that is formed by tectonic processes like plate movements, and later modified by glacial action through erosion and deposition of sediments. Fjords are typically found in regions that have experienced both tectonic and glacial activity, such as Norway and New Zealand.
Can you see the formation of glacial trough?
Yes, glacial troughs are U-shaped valleys that form through the erosion of moving glaciers. They have steep, straight sides and a flat bottom that was carved out by the glacier over time. The presence of a glacial trough indicates past glaciation in an area.
What are The glacial features that occur in swarms of long and smooth canoe-shaped hills?
The glacial features that occur in swarms of long and smooth canoe-shaped hills are called drumlins. Drumlins are typically formed under moving glaciers and indicate the direction of ice flow. They are important indicators of past glacial activity and can be found in large numbers clustered together in areas that were once covered by ice sheets.
Can you prevent glacial erosion?
Yes you can prevent glacial erosion. In an experiment in Italy, they put a white sheet of fleece the size of football fields over the glaciers. The glacier under the fleece blanket is melting much more slowly than the ice that is not covered by it.
