Glaciers: Shaping the Landscape

What physical effects do glaciers leave on the land?

Check all that apply.

A. Carve away land

B. Basins and lakes

C. Islands made out of sand

D. Volcanoes

Final answer:

Answer:

Glaciers shape the landscape by eroding land and creating basins and lakes through the deposition of materials. However, they do not form sand islands or volcanoes. Therefore, option A is correct.

Glaciers have a profound impact on the landscapes they traverse. As agents of erosion, they carve away land by scratching and grinding down rocks. This process can create spectacular landforms like U-shaped valleys and fjords. Glaciers also deposit materials they carry, which can lead to the formation of basins and lakes after the glacier retreats. Outwash plains and moraines are examples of landforms created by glacial deposition.

However, glaciers are not responsible for the formation of islands made out of sand or volcanoes; these are typically formed by other geological processes. They carve away land as they move, scraping and grinding down rocks. This process is known as glacial erosion. Glaciers also contribute to the formation of basins and lakes as they melt and leave depressions in the landscape. However, islands made out of sand and volcanoes are not directly caused by glaciers.
