Icebergs & Glaciers (Revised Edition)

It's hard to imagine that twenty thousand years ago, most of Earth was covered in ice. Today, icebergs and glaciers are found only in cold polar regions and on high mountains. These huge masses of ice have shaped our rivers, our mountains, and the landscape of our entire planet and still continue to do exactly that to this day.

In this updated edition, award-winning science writer Seymour Simon uses fascinating facts and breathtaking full-color photographs to break down how glaciers and icebergs are formed, how they move, and why they are important to our planet.
