Antarctica covers about 14,000,000 square kilometers and is larger in area than either Europe or Australia- and it's all because of the vast ice cap that covers 98% of the continent's surface. So, what would Antarctica look like if the ice was all gone? For one, it would be the smallest continent on Earth. But like the other lands, Antarctica would also have its share of mountains, plateaus, and valleys, too. Although not all of them are invisible to our eyes now, let's take a look at some of the physical features of this one and only continent- Antarctica. The continent of Antarctica is made up of two regions: the East Antarctica (often called the Greater Antarctica) and the West Antarctica (or the Lesser Antarctica). They are divided by the Transantarctic Mountains which crosses the entire continent from the Weddel to the Ross seas, covering an area of about 3,500 km long and 100 to 300 km wide. The biggest difference between the two regions is that the East Antarctica, could no doubt be called a continent, whereas the West Antarctica is a collection of islands held together by the massive ice cap. It is also known that the East and West has a difference in their geographic formation as well. The land of the East, with a region consisting of rocks that are more than 570 million years old, is older than that of the West where all the active volcanoes of Antarctica are found.
