From tides to marine life, it is an eye-opening introduction to the nature of oceans and what they contribute to life on Earth. The surface of our planet Earth is more than two thirds (72 percent) covered by water. We call small stretches of water 'seas' and larger expanses 'oceans,' but they are all part of one gigantic World Ocean that is moving and changing-and affecting our lives-all the time. Without seas and oceans, we would not survive. But where did all this water come from? What does it do? Why do we need it?
This fascinating guide to the world's oceans combines fact-packed, easy-to-read text with colorful and quirky illustrations. 40 pages, softcover.
