Antarctica is a land of ice. Almost the whole continent, which includes the South Pole, is covered with ice.
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, crash into the ocean, and float away to become icebergs. Some of the chunks are as big as a city!
At the opposite end of the Earth, there is an ice-covered ocean. It surrounds the Arctic, or North Pole. The ice cracks, crashes, and swirls on top of ocean currents. It shrinks in summer and expands in winter, but it never disappears. North and South, the polar regions of the Earth are weirdly beautiful places, frozen with ice.
