Have you ever noticed how blue Earth looks in photographs taken from space This is because of our oceans. Earth is the only planet in our solar system with water on its surface—more than 200 quadrillion tons of water—and it's constantly in motion. You don't have to live near the ocean to know its power. Changes in temperature far out in the sea can cause a drought thousands of miles away. The oceans affect us all. Award-winning science writer Seymour Simon brings you this full-color photographic introduction to the ocean! This nonfiction picture book is an excellent choice to share during homeschooling, in particular for children ages 6 to 8. It’s a fun way to learn to read and as a supplement for activity books for children. Seymour Simon knows how to explain science to kids and make it fun. He was a teacher for more than twenty years, has written more than 250 books, and has won multiple awards. This book includes an author's note, glossary, and index and supports the Common Core Learning Standards, Next Generation Science Standards, and the Science, Technology, Engineering, and Math (STEM) standards.
