What do shape do glaciers form?
Glaciers can form various shapes, including valley glaciers, ice sheets, and ice caps. Valley glaciers form in mountain valleys, while ice sheets cover vast areas of land. Ice caps are smaller ice masses that are typically dome-shaped and found in polar regions.
Is the formation of glaciers is directly controlled by climate?
Yes, the formation of glaciers is directly controlled by climate. Glaciers form in areas where snowfall exceeds snowmelt and evaporation, allowing the snow to accumulate and eventually compress into ice. A colder climate with consistent snowfall and cool temperatures is necessary for glaciers to form and grow.
What of These long narrow glaciers form between mountains and are common in the Alps and the Andes.?
These long narrow glaciers are called valley glaciers. They form when snow accumulates in a valley and slowly turns into ice, flowing downhill under the force of gravity. Valley glaciers are often found between mountains in regions like the Alps and the Andes.
Glaciers can only form when?
Glaciers can only form when snow accumulates over time and compacts into ice. This process requires a cold climate that allows the snow to persist without melting. Additionally, the weight of the ice must exceed the rate at which it melts or sublimates.
What are the two kinds of glaciers and how are they different?
The two main types of glaciers are alpine glaciers, which form in mountainous regions and flow down valleys, and ice sheets, which are massive continental glaciers that cover large areas of land. Alpine glaciers are smaller and more common, while ice sheets are much larger and thicker.
What can continental glaciers form?
Glaciers can form U shaped valleys.
When can glaciers form?
Glaciers form when the rate of snow fall exceeds the rate of melting.
What is Long narrow glaciers that form between mountains?
Valley Glaciers!
Is a glaciers a land form?
NO
Why don't glaciers form in Australia?
because austrailia has warm weather and warm weather does not cause glaciers to form
What are long narrow glaciers form between mountains and are common in the Alps and the Andes.?
valley glaciers
What Narrow glaciers form between mountains and are common in the Alps and the Andes.?
valley glaciers
How was Norway's jords form?
From glaciers.
How have glaciers helped form Long Island?
Glaciers have helped form Long Island in the sense that millions of years ago, the glaciers eroded the block of land that is now known as Long Island.
How are glaciers different from alpine glaciers?
They difference between them is where there flow. Continental glaciers are enormous ice sheets, and are found in Greenland and Antarctica. Alpine glaciers form in mountain valleys.
How are the glaciers of Antarctica different from valley glaciers?
They form a huge mass that covers the entire continent?
Glaciers form what percent of Freshwater?
25%
