Glaciers
Glaciers are large, dynamic bodies of ice that form over long periods of time when snow accumulation exceeds ice ablation. They are among the most significant forces shaping Earth's landscape over long time scales. Glaciers are currently found at Earth's poles and in mid-latitude and equatorial mountains.

How many meters deep is the Lambert Glacier?
According to its Wikipedia entry:
"Lambert Glacier is a major glacier in East Antarctica. At about 60 miles wide, over 250 miles long, and about 2,500 m deep, it holds the Guinness world record for the world's largest glacier."
What percentage on earth's surface is covered in glaciers?
it is 28% of the world was covered by glaciers.
28% of the earth was covered by Glaciers during the Ice Age.
What are all the scientists that study glaciers?
The scientific study of glaciers and their effect on the landscape say again
When was Mengele given the name Angel of Death?
Because of the cruelty of his "experiments," which resulted in the deaths of his "subjects."
It's called a "hanging valley". Many waterfalls occur at hanging valleys.
How much of the earths water is fresh water that is not frozen?
Very little of the water on earth is outside either the oceans or the polar ice caps. Only three percent of the water in the world is fresh, and of that:
- 26.5 million cubic kilometres or about 2.1 percent of all water is in the Antarctic Ice Sheet
- 3 million cubic kilometres or about 0.25 percent is in the Greenland Ice Sheet
- Most of the rest is in a few major lakes like Lake Baikal (23,600 km3 or one fifth of non-frozen water), Lake Tanganyika (18,900 km3), Lake Superior (11,600 km3) and Lake Malawi (7,725 km3).
- The proportion of the total water that is fresh and not frozen is very small, around 0.003 percent of all the water in the world.
Steep-sided, half-bowl shaped recesses carved into mountains at the heads of glacial valleys.
The Fjords: Steep cliffs, acting as ocean inlets.
Horn peaks: Where cirques intersect.
Terminal moraines: Piles of rocks.
Crevasses: Cracks in glaciers
Are glaciers carved basins that filled with water to form lakes?
No, glaciers form from snow that falls high in the mountains then consolidates and refreezes into ice under the weight of later snows. This ice and snow then flows down the mountains into valleys producing a characteristic U-shaped erosion pattern in those valleys.
What are 2 ways glaciers build up the land?
Glaciers are forces of erosion of the land they tend to do the opposite of build it up, they wear it down.
However they do deposit moraines and when they melt the land springs up a little.
Which New york state landscape region has the lowest elevation?
The New York state landscape region with the lowest elevation is the Atlantic Coastal Plain. This region stretches along the southeastern part of the state and features flat terrain characterized by beaches, wetlands, and low-lying areas. The elevation generally ranges from sea level to a few hundred feet above sea level, making it the lowest region in the state.
False. At the last glacial maximum, the southernmost reach of the glaciers was around central Ohio. The areas that are now Mexixo and the southern U.S. were free of continental glaciers.
Where are glaciers found on the planet?
Glaciers are found on every continent on Earth, with the largest concentrations in polar regions such as Antarctica and Greenland. They also exist in high mountain ranges like the Alps, Himalayas, Rockies, and Andes, where they are fed by snowfall and high elevations.
What are the major natural features in Antarctica?
The major natural feature is the ice sheet that covers 98% of the continent.
What results when tributary glaciers recede?
When tributary glaciers recede, they leave behind debris and sediment in the form of moraines. These deposits can reshape the landscape through processes like glacial erosion and deposition. The retreat of tributary glaciers can also lead to changes in river flow patterns and alterations in the ecosystems they once influenced.
