Glaciers
Wendell Tangborn, Marc Simont
eBook
A children's book about Glaciers. There are places on Earth where the snow never melts, not even in summer. Places where snow has piled deeper and deeper, year upon year, turning into thick layers of ice. Big fields of this ice are called glaciers.Today glaciers are found near the poles and in many mountain ranges, but thousands of years ago they were spread over large parts of the earth. They may even have covered the place where you live.How can you tell if glaciers shaped the land around you? You can look for sharply curved valleys, for long, low hills, or for a big, rounded boulder standing alone. All are signs that a glacier pushed across the land, grinding and crushing the things in the path, picking up soil and rocks, boulders and trees, and then dropping them as it melted.Wendell Tangborn's sparkling clear introduction to glaciers - how they form and move, and shape the land as they go - is beautifully supported by the icy majesty of Marc Simont's landscapes.
