East Antarctica facts for kids
East Antarctica, also known as Greater Antarctica, is the biggest part of the Antarctic continent. It makes up about two-thirds of the entire landmass! This huge area is located on the side of Antarctica that faces the Indian Ocean. It's separated from West Antarctica by the towering Transantarctic Mountains.
East Antarctica is famous for being one of the most extreme places on Earth. It holds the record for the coldest temperature ever recorded! It's also incredibly windy and very dry, almost like a desert.
This vast region includes many different areas. Some of these are Coats Land, Queen Maud Land, Enderby Land, Kemp Land, Mac. Robertson Land, Princess Elizabeth Land, Kaiser Wilhelm II Land, Queen Mary Land, Wilkes Land, Adélie Land, George V Land, Oates Land, and Victoria Land. Almost all of East Antarctica is found in the Eastern Hemisphere.

What Makes East Antarctica So Extreme?
East Antarctica is known for its incredibly harsh weather. It's not just cold; it's the coldest place on our planet! Temperatures can drop far below freezing, making it a very challenging environment.
The Coldest Place on Earth
Scientists have recorded the lowest natural temperatures here. This happens because the land is very high up, and the air above it is extremely dry. The clear skies allow a lot of heat to escape into space, making it super chilly.
Strong Winds and Dry Air
The winds in East Antarctica can be incredibly strong. These winds, called katabatic winds, rush down from the high ice sheet towards the coast. Even though it's covered in ice, East Antarctica is also one of the driest places. The air is so cold that it can't hold much moisture, and very little snow falls.
The Giant Ice Sheet
East Antarctica is covered by a massive ice sheet. This ice sheet is the largest in the world. It's so thick that it buries entire mountain ranges beneath it. If all this ice were to melt, global sea levels would rise significantly.
How the Ice Sheet Formed
The East Antarctic Ice Sheet has been growing for millions of years. Snow falls and compacts over time, turning into ice. This process has created an ice sheet that is, on average, about 2,500 meters (8,200 feet) thick. In some places, it can be even thicker!
Impact on Climate
The huge ice sheet of East Antarctica plays a big role in Earth's climate. It reflects a lot of sunlight back into space, helping to keep our planet cool. Changes to this ice sheet can affect weather patterns and sea levels around the world.
Exploring East Antarctica
Even though it's a harsh environment, scientists and explorers have been studying East Antarctica for many years. They learn about Earth's past climate by drilling into the ice. Ice cores can show us what the atmosphere was like thousands of years ago.
Scientific Research Stations
Several countries have built research stations in East Antarctica. These stations are home to scientists who study everything from geology and glaciology (the study of ice) to meteorology (the study of weather) and wildlife. Living and working in such extreme conditions requires special training and equipment.
Unique Wildlife (Limited)
While the interior of East Antarctica is mostly barren, some life can be found along its coasts. Penguins, seals, and various seabirds live in the colder waters and on the ice edges. They are specially adapted to survive in this icy world.
