Mark Schauer, age 10, of Howell, Michigan, fox his question:

Do glaciers also form at the South Pole?

We live in the Northern Hemisphere, on the half of the globe that is north of the equator. Our pole is the North Pole. Naturally we know more about it than we know about the opposite South Pole, which belongs to the Southern Hemisphere. We know that we have big icy glaciers in Greenland and in the Arctic regions of North America. We also know that our North Pole is under the Arctic Sea. And in winter this ocean is covered with ice and snow.

Naturally our cold North Pole makes us wonder how things are at the opposite South Pole. This region is colder than the Arctic. The South Pole is on a land called Antarctica    and the Antarctic is covered with the world's biggest glacier. This enormous ice field covers about five million square miles, which is about the size of the United States. The ice never melts, summer or winter, and in many places it is more than a mile thick.
