You might think of it as a giant peninsula. It stretches from the South Pole toward South America. It lies between the Ross Sea and the Weddell Sea. The Transantarctic Mountains act as a border. They separate West Antarctica from East Antarctica.

Most of this land is hidden under ice. This huge layer is the West Antarctic Ice Sheet. It covers almost everything in the region. The ice is very thick and wide. Some parts of this ice sheet are changing. Scientists see signs that the ice might be shrinking. This may happen because of climate change. The ice sheet has lost some of its mass recently. It is a very important part of our planet's ice.

People began using the name West Antarctica in the early 1900s. Names like Balch and Nordenskiöld are linked to this time. The name became standard after the International Geophysical Year. That special time for science was from 1957 to 1958. Explorers found that the Transantarctic Mountains were a great border. The Advisory Committee on Antarctic Names approved the name in 1962. This helped everyone use the same name for the region.

There are many specific places to find in West Antarctica. It includes King Edward VII Land. It also has offshore islands like Adelaide Island. You can find large ice shelves here too. The Filchner-Ronne Ice Shelf sits on the Weddell Sea. The Ross Ice Shelf sits on the Ross Sea.

Some parts of West Antarctica are not covered in ice. The coasts of the Antarctic Peninsula are ice-free in summer.

This area is called the Marielandia Antarctic tundra. It has the warmest climate in all of Antarctica. The rocks there are covered in moss and lichen. These small living things can handle the intense cold. They grow during a very short season. Even in summer, the weather stays very cold.
