POLES APART
Many are surprised to learn that Antarctica is nearly twice the size off the united states. Largely because of this difference, the climate of the two areas is very different. Antarctica is the coldest area in the world. At both poles, daily temperatures may drop for below the monthly mean. Partly because of this climatic difference, the land animals and plants of the two regions are very different. Ice is the great feature of Antarctica. More than 4,5 million square miles of ice sheet cover the area. The icecap is very thick, averaging nearly 8.000 feet. If this great volume of ice were to melt, the volume of the world oceans would increase, and sea level would rise.
