How did glaciers help shape the Northeast?
What are two ways that glaciers helped shape the Northeast? 1)Glaciers scraped away fertile soil and formed basins that filled with water to become lakes. 2)The glaciers scraped away topsoil which left behind poor, rocky soil.
How did glaciers affect North America?
The ice sheet stripped Canada of its topsoil, scoured and polished bedrock, and gouged out numerous future lake basins. The till and outwash were deposited to the south, forming the fertile farmlands of the United States. The ice carved out the Great Lakes basins, which are rimmed by end moraines.
Are there glaciers in the Northeast region?
Valley glaciers, flowing from the high mountains in the Adirondacks, Catskills and New England, originated near the peaks in bowl-shaped scours called cirques. Though the mountains are now free of glacial ice, the distinctive scoop-like cirques are still visible in some peaks in the Northeast.
What role did glaciers play in shaping the current physical geography of North America?
A glacier’s weight, combined with its gradual movement, can drastically reshape the landscape over hundreds or even thousands of years. The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.
What glaciers leave behind?
Later, when the glaciers retreated leaving behind their freight of crushed rock and sand (glacial drift), they created characteristic depositional landforms. Examples include glacial moraines, eskers, and kames. Drumlins and ribbed moraines are also landforms left behind by retreating glaciers.
Why is the presence of ice important to Earth’s climate?
Snow and ice are an important part of the global climate system. Acting like a highly reflective blanket, the cryosphere protects Earth from getting too warm. The presence or absence of snow and ice affects heating and cooling over the Earth’s surface, influencing the entire planet’s energy balance.
What sort of snow turns into a glacier?
