A glacier is a large mass of ice and snow that forms where snow falls at a greater rate than it melts.
Glaciers usually move slowly down the slopes of mountains or through valleys. They break up into icebergs when they reach the sea.
It shouldn’t be surprising that the largest glacier on earth is found in Antarctica, the “frozen continent”. There are many large glaciers in Antarctica, some more than 100 miles long. The largest by far is the Lambert Glacier.
This moving ice sheet is up to 40 miles wide, and it extends for a distance of some 270 miles. Imagine a single sheet of ice reaching all the way from New York City to Buffalo, New York!
