Earth's Polar Regions

Do you wonder what Earth's Polar Regions are like? Where do polar bears live? Where do penguins swim? Why does the Sun never shine in winter in the Arctic? Why does aurora occur near the Earth’s Poles? How big are the Earth’s ice caps, and are they changing? The Earth’s Polar Regions are hosts to unique phenomena and ecosystems – both fascinating and beautiful. Explore the Earth’s Arctic and Antarctic through the links in this section.
