How do drumlins and eskers form?
Drumlins and eskers are landforms created by glacial activity. Drumlins are elongated hills formed by the movement of glacial ice, which shapes the underlying sediment into a streamlined form as the glacier advances and retreats. In contrast, eskers are long, winding ridges of sediment deposited by meltwater streams that flow beneath or within a glacier, leaving behind layers of sand and gravel as the glacier retreats. Both features are indicators of past glacial processes and provide insights into the dynamics of ice movement.
How do a moraine form?
A moraine forms as a result of glacial activity, specifically through the accumulation of debris that glaciers transport and deposit. As a glacier moves, it erodes the landscape, picking up rocks and sediments, which are then carried along. When the glacier retreats or melts, it leaves behind these materials, creating a ridge or mound known as a moraine. There are different types of moraines, such as terminal moraines at the glacier's end and lateral moraines along its sides.
What is the noun form of the verb require?
The noun forms of the verb 'require' are requirement and the gerund, requiring.
Why are crevasses only 40m deep?
Crevasses are typically around 40 meters deep due to the balance between the glacier's movement and the structural integrity of the ice. As glaciers flow, stress builds up, causing cracks to form. However, beyond a certain depth, the ice's weight creates enough pressure to prevent further cracking, leading to a natural limit in depth. Additionally, deeper crevasses would require more significant ice deformation, which is less common in stable glacier environments.
What is the Radical form for the square root of 1300?
The radical form is √1300. It is possible to simplify that but the question does not require simplification.
Is 'glacier' a noun?
Yes, glacier is a noun. "Glacial" is the adjective form.

Escher's are glacial features formed when .?
Escher's are glacial features formed when meltwater streams underneath a glacier, creating tunnels and channels that can collapse to form depressions on the glacier's surface. These features can disrupt or alter the glacier's flow and structure.
Ridges that form along the sides of glacial valleys as a glacier melts are called what?
Ridges that form along the sides of glacial valleys as a glacier melts are called moraines. Specifically, lateral moraines are found along the edges of a glacier, while terminal moraines accumulate at the glacier's end. These features are composed of debris and sediment that the glacier has transported and deposited as it advances and retreats.
What is formed when glacial eroion?
Glacial erosion can form various landforms like cirques, arêtes, and valleys. As glaciers move, they pick up rocks and debris, which can carve out shallow grooves known as striations on the underlying rock. When the glacier retreats, it leaves behind moraines made up of this debris.
Unsorted rocky debris that is formed by a melting glacier called?
The unsorted rocky debris formed by a melting glacier is known as glacial till. This mixture of rock fragments of various sizes and shapes is deposited by the glacier as it retreats, with no specific order or arrangement. Glacial till can form different landforms, such as moraines or drumlins, depending on how it is deposited.
How do glacial valleys form?
Glacial valleys form through the process of glacial erosion, where the movement of a glacier carves and shapes the valley over time. As the glacier moves downhill, it picks up rocks and sediments, which act as abrasives that wear away the underlying rock. The downward pressure and friction of the glacier further deepen and widen the valley, creating a distinct U-shaped profile.
What glacial feature causes piles of rocks?
The glacial feature that causes piles of rocks is known as a "moraine." Moraines are formed from the debris (such as rocks and sediment) that glaciers transport and deposit as they move and melt. There are different types of moraines, including terminal moraines, which mark the furthest advance of a glacier, and lateral moraines, which form along the sides of a glacier. These piles of rocks can create distinct landforms in glaciated regions.
What of the following glacial features results from deposition a moraine?
Glacial moraine could dam and prevent glacial meltwater from escaping. Glacial lakes usually form behind the moraine as the thawing glacier retreats.
Where does glacial till collect on a glacier?
Glacial till collects at the base and along the margins of a glacier as it moves and grinds down underlying rock and sediment. This debris, which comprises a mixture of clay, silt, sand, gravel, and boulders, accumulates in areas where the glacier is melting or retreating. Additionally, till can form ridges known as moraines at the edges of the glacier, marking its past positions. Overall, glacial till is a key indicator of glacial movement and erosion processes.
How do glacial form?
Glacial erratics aren't exactly formed. They were deposited by glaciers that were moving in that area at one time. improved= Glacial erratics are exactly formed. Because a glacier is so heavy, the glacier can pluck large rocks as the glacier moves. When the rock is too heavy for the glacier to hold, or the glacier is retreating, it then deposits the rock in a place where it wouldn't usually be found. This is what an erratic is. A large piece of rock in an unusual surrounding. i hope this helps :)
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.
