Glaciers are large bodies of ice formed from snowfall accumulating over thousands of years. They cover approximately 20% of Earth’s land surface and are found in every continent except Australia.
Glaciers are classified into three main types:
- Continental Glaciers
- Marine Glacial Deposits
- Alpine Glaciers
Continental glaciers form where two tectonic plates collide, such as at the edge of the Himalayas. Marine glacial deposits form along ocean shores, such as those around Iceland. Alpine glaciers form in high-altitude areas, such as the Alps.
Lambert Glacier is the largest glacier in the world. It drains 8% of the Antarctic ice sheet. It flows into Amery Ice Shelf from Prydz Bay.
It is about 270 miles (435 kilometers) long, and its largest point is about 60 miles (96 kilometers) wide. At its deepest point, the glacier is 8,200 feet (2,500 meters) deep.
The Lambert Glacier was named by the Antarctic Names Committee of Australia in 1957 after Bruce P. Lambert, Director of National Mapping in the Australian Department of National Development.
The Lambert Glacier is important in the study of climate change because of the harsh conditions in the area.
What are Land Glaciers
Glaciers are massive bodies of ice that form in the polar regions of the world. They are made up of fallen snow and ice, and they move slowly down from the pull of gravity.
Glaciers formed during the Ice Age that ended 10,000 years ago.
Difference between ice caps and glaciers
Ice caps and glaciers are two types of landforms that cover large areas of Earth. They both consist of frozen water, but they differ in size and shape.
Glaciers are long, narrow bodies of ice that flow slowly down mountains or hillsides. They form when snow accumulates at high elevations and then gradually melts during the summer months. As the glacier moves downhill, it picks up speed and eventually reaches the bottom of its valley.
Ice caps, on the other hand, are much larger than glaciers and cover a wide area. They are formed when cold air from the Arctic Ocean meets warm air from the tropics. The result is a layer of dense, heavy fog that covers the entire planet.
Glaciers are slow-moving, whereas ice caps move very rapidly. Both are important because they affect global climate change.
How is sea ice different from glacial ice
Sea ice melts in the ocean, while glaciers melt on land, contributing to global sea-level rise.
Sea ice melts in the Arctic, and this can have devastating consequences for walrus and polar bears.
Sea ice in the Arctic is melting faster than anywhere else on Earth, and this is changing the circulation of the Atlantic Ocean, causing more destructive storms and hurricanes around the planet.
Icebergs are chunks of glacial ice that break off the glaciers and fall into the ocean, contributing to global sea-level rise.
When Arctic sea ice melts, it changes the weather system around the world by altering the pattern of the jet stream.
Is the Antarctic ice sheet growing or shrinking
Climate models predict sea ice shrinking in the Arctic and Antarctic regions, but observations show ice extent in the Antarctic region is increasing.
The Antarctic continent is surrounded by seasonal, floating sea ice, which effectively doubles the size of Antarctica in winter.
Although the Arctic’s sea ice extent is decreasing, sea ice is growing in Antarctica.
The Arctic and Antarctic sea ice are very different. The Arctic sea ice is thick and multi-year, whereas the Antarctic sea ice is a thin and single year.
In autumn, the sea ice extent is larger than the ice-covered area, and this may be related to changes in ice drift and wind patterns.
