• 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

• 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

• Sticks and Stones
• Instead 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.
