explanation[1]="The Northern Hemisphere and Southern Hemisphere have opposite seasons - when it is winter in one, it is summer in the other. This is due to the tilt of the Earth, and which part of the Earth is tilting toward the sun at a given time. Antarctica is in the Southern Hemisphere and its summer occurs from October through February. During this time, \"summer\" temperatures rarely go above freezing, even though the sun never sets below the horizon and there are 24 hours of daylight each day!"

explanation[2]="In the early 1900\'s there was a race among nations to see who could be the first to reach the South Pole. In 1911, Roald Amundsen from Norway reached the Pole only one month before Captain Robert F. Scott from England. He, his crew, and nearly 100 sled dogs set up a small hut on the coast of Antarctica and journeyed inland to the Pole."

explanation[3]="The coldest temperature ever recorded on Earth was measured at the Russian Vostok Research Station in Antarctica. A temperature of −128.6 F was recorded there on July 21, 1983, during the middle of Antarctica\'s winter. "

explanation[4]="Greenland (near the North Pole) and Antarctica are the only places on Earth that have ice sheets. Ice sheets are huge glaciers that slowly move over large areas of land. Antarctica\'s sheet is one to two miles thick! It slowly moves over the continent, starting from the middle and moving out in all directions toward the sea."

explanation[5]="Polar bears only live in the Arctic (near the North Pole). Penguins and Weddell seals only live in the Antarctic (near the South Pole). But killer whales, or Orca, are found in every ocean on Earth. They especially like feeding in the cold waters of the Arctic and Antarctic."
