Glaciers form in higher elevations and polar regions where the rate of snowfall exceeds the melting rate of the snow. As the snow accumulates, the pressure caused by the weight of the overlying snow causes it to recrystallize into ice. Eventually the ice can become so heavy that it starts to move downward under its own weight.

∙ 10y agoGlaciers can only form in very cold places because in order to stay in their glacial form, the snow cannot completely melt away. A cold climate is necessary so that the layers of snow will continue to get thicker and thicker. When the snow does melt, it will freeze again and turn into ice.

∙ 10y agoGlaciers form only on land (including on oceanic islands in some cases) because on the deep sea ice floats above the water and cannot accumulate. This is because ice accumulating on sea would insulate the lower sea from freezing, so that even at the North Pole sea ice is no more than 0.1 percent as thick as the ice sheet at the South Pole. Sea ice inevitably flows away from where it forms even if more snow falls than is melted.

Is polar climate colder than subarctic climate?
the subarctic is colder than the tundra
What are the seasonal temperatures for the Arctic and the Antarctic?
Both polar regions are cold. Antarctica is so cold that it cannot sustain life -- about 30 degrees F colder than the Arctic. Cold in this comparison means generally below freezing -- all year.
What are two ways Polar Regions and Deserts alike?
The Arctic and Antarctic oceans are both near a pole of the Earth.The Antarctic and Arctic oceans are both cold, dark, remote, and close to the Earth's poles.The Arctic, as well as the Antarctice, are both cold and dark.
How many species of freshwater sponges are there?
I think most of these sponge species live in aquatic habitats. Such as cold oceans in the Arctic and Antarctic, but few live in warmer climates. About 150 of the sponge species live in warm climates, like tropical areas, while most live in cold areas.
Which US regions are the coldest?
The Polar Regions. Obviously, they are at the north and south poles which are also the Arctic and Antarctic Circles.
What is One of the largest dry regions on the earth?
The Antarctic or the Arctic, too cold to rain
Is polar climate colder than subarctic climate?
the subarctic is colder than the tundra
How are the Arctic and antarctic alike?
their both cold
What are the seasonal temperatures for the Arctic and the Antarctic?
Both polar regions are cold. Antarctica is so cold that it cannot sustain life -- about 30 degrees F colder than the Arctic. Cold in this comparison means generally below freezing -- all year.
Can Arctic foxes live in the Antarctic?
No, the Antarctic has a very cold climate and has no terrestrial food chain to support Arctic foxes.
What parts of the world are not inhabited by bees?
The arctic and antarctic (too cold), and in deserts (no flowers).
What is the climate in the arctic and the antarctic?
Cold, with little precipitation.
Why there isn't any crocodiles live in Europe and antarctic?
to cold of climates
What do penguins and polar bears have in common?
Both polar bears (which live in the Arctic) and emperor penguins (which live in the Antarctic) are adapted to living in arctic climates. They both depend upon the presence of polar ice shelves.
What domain do archeabacteria belong to?
Bacteria in the domain Archaea are usually found in extreme climates, such as extreme hot(volcanos) or extreme cold (arctic or antarctic).
What are two ways Polar Regions and Deserts alike?
The Arctic and Antarctic oceans are both near a pole of the Earth.The Antarctic and Arctic oceans are both cold, dark, remote, and close to the Earth's poles.The Arctic, as well as the Antarctice, are both cold and dark.
Do foxes live in cold climates?
Yes, Arctic foxes do.
