• Not many people live on mountains, but mountains are important to all of us. Mountains create rain forests and deserts. Mountains store water on their snowy peaks and release it in rivers that make the valleys below green and fertile. Many farms and cities depend on mountain lakes for their drinking water, and the rivers are often harnessed to manufacture electricity. Mountains offer a chance for people to climb or ski or just take pleasure from some of the most spectacular scenery in the world.-Taken from Mountains by Seymour Simon

• Scientists call the splitting of icebergs “calving.” Icebergs are a lot larger than a calf, though. Icebergs as large as a ten-story building are not unusual. One of the largest Antarctic icebergs that formed recently is 185 miles long and 25 miles wide.-Icebergs Floating Snow Cones

SUPPORTING DETAILS

Sticks and StonesInstead of coloring that helps them blend into the

environment, some animals have disguises that make them look like other living or nonliving things. Some katydids (a kind of grasshopper) look almost identical to leaves. Insects known as phasmids look like sticks or leaves.

The pebble plant, which grows in southern Africa, escapes the attention of ostriches and other animals that might like to eat it because it looks like stones scattered on the desert floor. Some species of spiders and moths escape enemies because they look like bird droppings. Some leaf beetles look like caterpillar droppings.
