|Icebergs and Glaciers— Seymour Simon
Published by William Morrow/HarperCollins, 1987.
The giant rivers of ice called glaciers move ever so slowly, but they are powerful enough to grind and crush everything in their paths. The land is carved and shaped as they move. Large pieces of ice that break away from glaciers are called icebergs. They can be 80 to 100 feet high and several miles long! Seymour Simon's exploration of the world of ice includes beautiful photographs and a discussion of how glaciers are formed, how they move, and how they alter the land's shape.

glacier A large mass of ice flowing very slowly through a valley or spreading outward from a central point. Glaciers form over many years from packed snow in areas where snow piles up faster than it melts. A glacier is always moving.
During the last Ice Age, some 10,000 years ago, much of North America was covered by glaciers that were over a mile thick. South America, by contrast, did not get covered by glaciers except in the Andes mountains.
global warming A rise in the average temperature of the Earth's atmosphere. Many scientists believe that global warming is caused by the release of greenhouse gases. Global warming is believed to be capable of causing major changes in weather patterns.
greenhouse effect The trapping of the Sun's heat in the Earth's atmosphere. The greenhouse effect is caused by the presence of greenhouse gases in the atmosphere. Many scientists believe it is the main cause of global warming.
greenhouse gas A gas in the atmosphere that makes the greenhouse effect worse. Carbon dioxide, water vapor, and methane are greenhouse gases.
