There are a great many mountains in Antarctica, many of them mostly buried by ice.

The highest Antarctic peak is Vinson Massif at 5,140 metres.

The second highest Antarctic peak is Mount Tyree at 4,852 metres.

The Transantarctic Mountains are the dominant mountain range stretching from one side of the continent to the other. It is over 2,200 km long with many peaks over 4,000 metres.

In January 2008, a previously unknown and unnamed Antarctic volcano erupted blowing a substantial hole in the ice sheet and shot gas and ash 12 km into the air. The volcano, which had not erupted for about 2,300 years, is located close to the Pine Island Glacier. It is said to be the biggest eruption in Antarctica for 10,000 years. Scientists said it may explain the speeding up of historically slow-moving glaciers in the region.

Until recently, Mount Erebus was the only active volcano on Antarctica. Other inactive volcanos include Mount Terror, Mount Bird and Mount Terra-Nova. There are about 20 inactive volcanos on Antactica.
