Antarctica is a frozen land. Ice covers almost all of the continent, which includes the South Pole.
The ice is several miles deep in places, covering all but the very tops of the highest mountains. Near the coast, glaciers crawl down the mountains and flow into the ocean. Glaciers are slow-moving rivers of ice and snow. Sometimes, chunks of the glaciers split off and crash into the ocean. They float away and become icebergs. Some of the chunks are as big as a city!
On the opposite side of Earth, an ice-covered ocean surrounds the Arctic, or North Pole. The ice cracks, crashes, and swirls on top of the currents. It shrinks in summer and expands in winter. But it never goes away. North and South, the polar regions of the Earth are strange and beautiful places.
