Glaciers create various landforms such as U-shaped valleys, moraines, drumlins, and fjords through processes like erosion, deposition, and melting. For example, as glaciers move, they erode the land beneath them, forming U-shaped valleys. When glaciers retreat, they leave behind piles of debris called moraines. Drumlins are elongated hills formed by glaciers depositing sediments, and fjords are deep, narrow inlets created by glaciers moving through valleys and subsequently melting.
Advancing glaciers are glaciers that are moving forward and expanding, while retreating glaciers are glaciers that are melting and shrinking. Stationary glaciers are glaciers that are not currently advancing or retreating, maintaining a relatively stable position.
Yes, for over thousands of years snow, ice and glaciers have been slowly moving. In the process they make a deep valley or gorge from all the erosion.
V-valley refers to a type of valley on a topographic map that has a V-shaped profile, typically formed by erosion from a river or stream. U-valley refers to a valley with a U-shaped profile, typically formed by glacial erosion. V-valleys are more narrow and have steeper sides compared to U-valleys.
As glaciers move, they can carve out deep depressions in the land called cirques. When the glacier retreats or melts, these cirques can become filled with water, forming lakes. Glaciers can also create moraines, which are piles of debris that dam up valleys, creating lakes behind them.

Valleys can be formed by a combination of erosion and weathering. Erosion, which is the process of wearing away rock and soil, contributes to the shaping of valleys by moving sediment and carving out the land. Weathering breaks down rocks and contributes to the gradual formation of valleys over time.
A slow-moving river of ice is called a glacier. Glaciers form when snow accumulates and compresses into ice over time, flowing downhill under the force of gravity. Glaciers can carve out valleys, carry debris, and shape the landscape as they move.
Glaciers can carve out valleys and fjords as they slowly move over the land, eroding the landscape. They can also deposit sediment as they melt, forming moraines and drumlins. Additionally, glaciers can reshape the land by creating features like cirques, aretes, and U-shaped valleys.

The scratch marks on rocks left by moving glaciers are called glacial striations. These marks are typically parallel and indicate the direction in which the glacier was moving.
A slow-moving body of ice is called a glacier. Glaciers form over time as snow accumulates and compacts into ice. They can carve out valleys, shape the landscape, and contribute to rising sea levels as they melt.
Yes, valleys can cause erosion. The flow of water through valleys can carve out the land, carrying away soil and rock particles. Additionally, glaciers moving through valleys can also contribute to erosion by grinding and transporting material.
Glaciers modify a valley by moving and eroding the landscape as they advance and retreat. They carve out deep U-shaped valleys through a process of abrasion and plucking, leaving behind distinct features such as cirques, moraines, and hanging valleys. The presence of a glacier can drastically reshape the valley's topography over time.
Valley glaciers are found in mountain valleys and are smaller in size compared to continental glaciers, which are massive ice sheets that cover large land areas. Valley glaciers move down mountains and shape U-shaped valleys, while continental glaciers can cover entire continents and reshape landscapes with their immense weight and movement.

Water is the most dominant agent of erosion on Earth. It shapes the Earth's surface through processes such as rivers carving out valleys, waves eroding coastlines, and glaciers moving and shaping the landscape.
