When multiple glaciers start their downward flow from a single point what do they create?
When multiple glaciers flow downward from a single point, they create a feature known as a "piedmont glacier." This occurs when the glaciers spread out and merge as they move into a broader lowland area, often resulting in a lobe-like formation. Piedmont glaciers can significantly reshape the landscape by eroding and depositing sediments as they advance and retreat.
Continental glaciers make landforms such as?
Continental glaciers create a variety of landforms, including moraines, which are ridges of debris left behind as glaciers advance and retreat. They also form drumlins, which are streamlined hills shaped by glacial movement, and kettles, which are depressions that result from melting ice blocks. Additionally, continental glaciers can carve out large basins and fjords, reshaping the landscape significantly. These features reflect the dynamic processes of glacial erosion and deposition.
Are glaciers that drop rocksandand other debris forming landforms called morains weathering?
No, glaciers that drop rocks and debris form landforms called moraines, but this process is not considered weathering. Weathering refers to the breakdown of rocks and minerals due to various factors like temperature changes, water, and biological activity. Moraines are created through the accumulation of material that glaciers transport and deposit as they advance or retreat.
When glaciers move over land dragging soil with them what is this known as?
When glaciers move over land and drag soil with them, this process is known as glacial erosion. As glaciers advance, they scrape and carve the underlying rock and soil, transporting sediments and debris. This results in the formation of various landforms, such as U-shaped valleys and moraines, which are accumulations of the material carried by the glacier.
What are glaciers and how do they change the geography of a region?
Glaciers are large masses of ice that move slowly over land. They shape the landscape by eroding rocks and soil, creating valleys, fjords, and lakes. As glaciers advance and retreat, they leave behind moraines, drumlins, and other landforms that reshape the geography of a region.

What is 2 ways that glaciers erode the land?
Glaciers erode the land through plucking, where they pick up and remove rock fragments as they move, and abrasion, where they scrape and grind the underlying bedrock as they advance. These processes help to shape landforms such as valleys, cirques, and moraines.

How have glaciers changed earth?
Glaciers have significantly shaped Earth's landscape through processes like erosion and deposition. As they advance and retreat, they carve valleys, create fjords, and form landforms such as moraines and drumlins. Additionally, glaciers store vast amounts of freshwater, influencing sea levels and ecosystems. Their melting due to climate change is also contributing to rising sea levels and altering habitats worldwide.
What effects do glaciers have on Canadian landscape?
Glaciers have significantly shaped the Canadian landscape through processes of erosion and deposition. As they advance and retreat, they carve out valleys, create fjords, and leave behind distinctive landforms such as drumlins and moraines. The movement of glaciers also redistributes sediment, contributing to fertile soil in some areas while forming rugged terrain in others. Additionally, the melting of glaciers contributes to changes in hydrology and can impact ecosystems and water resources in Canada.
What are mounds or ridges of till?
Mounds or ridges of till are glacial landforms formed when glaciers deposit large quantities of unsorted sediments, called till, as they advance and retreat. These features can take various shapes and sizes and are typically found in areas where glaciers have recently melted or receded, highlighting the glacier's path of movement.
Why are glaciers capable of eroding moving and depositing large amounts of rock material?
Glaciers are capable of eroding, moving, and depositing large amounts of rock material due to their immense weight and the movement of ice. As glaciers advance, the pressure can cause them to fracture and grind the underlying rock, a process known as abrasion. Additionally, the melting ice can carry sediment and debris, which is then transported as the glacier moves. When glaciers retreat, they deposit this accumulated material, forming various landforms such as moraines and outwash plains.
What range of particles can be carried by glaciers?
Glaciers can carry a wide range of particles, from fine silt and clay to large boulders. The size of the particles transported depends on the glacier's movement and the forces acting on it; smaller particles can be suspended within the ice, while larger debris can be dragged along the glacier's base. As glaciers advance and retreat, they can also deposit these materials, contributing to the formation of landforms like moraines and outwash plains. Overall, glaciers act as powerful agents of erosion and transportation in the landscape.
When and how do glaciers advance?
Glaciers advance when snow accumulation exceeds melting and sublimation. This typically happens during periods of increased snowfall or decreased temperatures. As more snow accumulates, it compresses into ice and causes the glacier to move forward.
