Frequently Asked Questions About what condition is most necessary to build a glacier?
If you have questions that need to be answered about the topic what condition is most necessary to build a glacier?, then this section may help you solve it.
What elements must exist for a glacier to form?
Three factors are required for the formation of glacial ice: (1) a cold local climate (polar latitudes or high elevation); (2) a lot of snow; more snow falls than melts; and (3) snow that is not removed by avalanches or wind.
What circumstances must exist for a glacier to form?
b>Temperatures must be low enough to keep snow on the ground year-round./b> c) Moisture must be present, brought by moisture-laden winds. d) A lot of snow must be present, snow that does not melt away in the summer, in order for a glacier to form.
What circumstances cause a glacier front to advance?
Glaciers move forward and backward; if more snow and ice are added than are lost due to melting, calving, or evaporation, glaciers will move forward; if less snow and ice are added than are lost, glaciers will retreat.
What is required for glaciers to endure and expand?
A region’s annual snowfall accumulates over time and does not completely melt in the summer, which causes the snow to gradually compress under its own weight into a massive mass of ice, which is how glaciers form.
What factors affect the glaciers?
The formation of a glacier takes millennia, and its size varies depending on the amount of ice it retains over the course of its lifetime.? the climate, whether polar, tropical, or temperate; and their thermal conditions, whether cold, hot, or polythermal base.
What 3 characteristics were created by glaciers?
U-shaped valleys, fjords, and hanging valleys are examples of the types of valleys glaciers can erode. Glaciers carve a set of distinctive, steep-walled, flat-bottomed valleys.
What elements affect a glacier’s ability to do its job?
Slope, ice thickness, snowfall, longitudinal confinement, basal temperature, meltwater production, and bed hardness are some of the variables that affect glacial speed.
A continental glacier needs to form from which of the following?
Snow can accumulate over time in regions that do not experience seasonal warming, and if the snow accumulates in great quantities, it can compact under its own weight and form ice. Continent glaciers can form and grow when climate conditions in a region cool over prolonged periods of time.
What causes glacial till to form?
When glaciers begin to melt or retreat, the sediment is deposited as unsorted glacial till, frequently in distinctive landforms like moraines and their associated sedimentary facies. Glaciers erode and transport rock as they flow down slope.

Do glaciers form higher or lower in elevation?
Five glaciers span more than 5,000 meters in elevation, 15 over 4,500 meters, and more than 30 over 3,000 meters. The glaciers of large and intermediate size originate at very high altitudes, and many of them descend much lower than elsewhere in the subtropics.
What are the two things that influence a glacier’s size?
Snowfall determines how large a glacier will eventually become, while melting can cause a glacier to recede. Global warming is the biggest influence on glacier size.
What fuels a glacier’s expansion?
Growing. In polar and high-altitude alpine regions, glaciers typically accumulate more snow in the winter than they lose from melting, evaporation, or calving in the summer. Glaciers form when snow accumulates over time, turns to ice, and starts to flow outward and downward under the pressure of their own weight.
What could make the glacier enlarge over the course of a year?
Snowfall and temperature are the main factors that cause a glacier to change in size. Images taken in 2008 were compared to images taken in 1999, and scientists discovered that glaciers grew an estimated 0.36 to 0.72 feet each year.
What elements influence glaciers?
Glaciers and ice sheets are also greatly influenced by other factors, such as the ocean water that surrounds them, the terrain (both land and ocean) over which they move, and even their own meltwater. This is true even though warm air undoubtedly melts the surface of glaciers and ice sheets.
What elements affect the development and movement of glaciers?
Other factors that affect a glacier’s velocity include the roughness of the rock surface (friction), the amount of meltwater, and the weight of the glacier. Glaciers in temperate zones tend to move the fastest because the ice along the base of the glacier can melt and lubricate the surface.
What impact does temperature have on a glacier’s size?
It may seem obvious, but temperature has a significant impact on glaciers; warmer annual temperatures are associated with smaller glaciers. Scientists have long argued over what determines glacial size, whether it be annual snowfall, humidity, UV radiation, or something else.
