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.
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 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.
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.
Is an ice glacier powerful?
Yes, glaciers can be powerful in terms of shaping and reshaping landscapes through processes like erosion and deposition. Glaciers can carve out valleys, move massive boulders, and leave behind distinctive landforms as they advance and retreat.

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 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.
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.

Yes, glaciers can be powerful in terms of shaping and reshaping landscapes through processes like erosion and deposition. Glaciers can carve out valleys, move massive boulders, and leave behind distinctive landforms as they advance and retreat.
What effect do glaciers do on the drainage of the shield?
Glaciers can reshape the drainage patterns of a shield by eroding the landscape and creating new channels for water flow. As glaciers advance and retreat, they can leave behind moraines and other landforms that affect how water drains across the shield. Melting glaciers can also increase water flow, leading to changes in drainage patterns.
In what ways did the glaciers change earth's surface?
Glaciers have significantly shaped Earth's surface through processes such as erosion, transportation, and deposition. As glaciers advance and retreat, they carve out valleys and fjords, creating distinct landforms like U-shaped valleys and moraines. They also transport sediment and rock fragments over vast distances, depositing them as glacial till when they melt. These processes contribute to the formation of unique landscapes and alter ecosystems, impacting climate patterns and biodiversity.
Where do glaciers depost the earth and rock as they move forward and advance?
Glaciers often push earth and rock from beneath themselves as they move forward. Many natural lakes were formed by glaciers carving the earth as they passed.
3 facts about glaciation?
glaciers move with tremendous force, glaciers advance and retreat, and last but not least, they covered all of Canada and some of New York city :)
