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.
How does glacial erosion affects the shape of the land?
Glacial erosion can carve out deep valleys, create U-shaped valleys, and leave behind moraines and drumlins. The movement of glaciers erodes rock and soil, shaping the land through processes such as abrasion and plucking. As glaciers flow over the landscape, they can significantly alter the topography by creating features like cirques and fjords.
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.
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.
What is a glacial trough and how does it form?
A glacial trough is a U-shaped valley carved out by a glacier as it moves downhill. It forms through a process called glacial erosion where the glacier scours and deepens the valley over time by plucking and grinding the bedrock beneath it. The vast weight and movement of the glacier cause it to scrape and shape the landscape into a distinctive U-shaped trough.
Is the grand canyon a glacial trough?
No. The Grand Canyon was carved by the Colorado River.
What is five letter word for glacial ice formation?
esker
Type of glacial formation making long island left after the glaciers receded from northern jersey and southern new york?
Glacial Moraine
What is the movement of glacial ice called?
The movement of glacial ice is called glaciation or glacial flow. Glaciers move due to the force of gravity and the deformation of the ice under pressure. This movement can result in the formation of features like moraines, crevasses, and glacial valleys.
The gouging of bedrock by rock fragments dragged by glaciers results in?
These are known as striations. Please see the related link.
Which of the following resulted in the formation of yosemite valley in the sierra nevada?
Glacial erosion
Is a glacial lake a result of deposition or erosion?
A glacial lake is typically a result of both erosion and deposition. Glacial erosion carves out depressions in the landscape, creating basins where water accumulates. Meanwhile, glacial deposition can form moraines or other features that dam up water and contribute to the formation of a glacial lake.
Hanging valley and a glacial trough?
Glacial Trough (U-shaped valleys) - Flat-bottomed valley with steep sides produced by the erosion of the floor and sides of the valley by an alpine glacier as its sediment abrades while the glacier flows downhill. On the topographic maps they are recognized by closely spaced contours along the valley sides and widely spaced contours on the valley floor.Hanging Glacial Troughs - Formed when the down-cutting erosion of the main valley glacier exceeds that by the tributary glacier. The tributary glacier flows onto the main glacier and thus has an erosional base level of the elevation of the main valley glacier. After melting, the lower portion of the tributary glacial trough is then left hanging above the main floor of the glaciated valley. On maps they are recognized by more widely spaced contours across a stream in the upper portion than in the lower portion (where the modern stream cascades into the main valley below).
What is Glacial Deposition and one example?
Glacial deposition is the process by which glaciers transport and deposit sediments, rocks, and other materials as they move. One example of glacial deposition is the formation of moraines, which are long ridges of material left behind by a glacier as it retreats.
What does see-sawin' mean?
See while you are sawin . . What does trough mean?
When a glacier leaves behind a rock that is a completely different material composition than the formation it is deposited upon it is called what?
Glacial till is unsorted sediment deposited directly by glacial ice.
