The combined land area of all of the continents is approximately 108,526,850 sq km.
The continent of Antarctica covers about 10% of the earth's surface. It is about as large as USA and Mexico combined.
The sea ice around the continent -- 10% of the earth's surface -- freezes during the austral winter, thus practically doubling the size of the continent.
The Moon's size isn't all that big. The surface area of the Moon is about the size of the African continent.
Antarctica covers about 9% of the Earth's land surface, which is about 3% of the total surface, or about 14 million square kilometers. It is about as 1.5 times as big as the US.
Africa covers approximately 20.4% of the total land area on Earth, making it the second largest continent after Asia.
Because it is under the ocean.
The Antarctic ice sheet covers about 98% of the Antarctic continent and at 27 million cubic km is the largest single mass of ice on Earth (90% of all the ice on Earth). This ice represents approximately 61% of all the fresh water on the Earth.
No much. Average humidity on the continent is five percent. It is the driest continent on earth.
Antarctica is a continent that covers 10% of the earth's surface. The continent is covered by ice -- about 98% of the continent in fact. This means that the continent is the continent; the ice is the ice, and zero percent of the continent is ice, but 100% of the ice is ice.
Deserts cover about 33% of the earth's land surface.
How much of the earth's surface do mountains cover? it is 99% of the earth
the surface of the moon is 0.074 of earth's surface area
