How the Oceans Work

Dive into the deep blue and discover the hidden secrets of our planet's oceans! Did you know that oceans cover more than 70 percent of the Earth, yet most of us know so little about them? This book explores the fascinating story of our oceans, from their birth to their eventual demise.

Let's investigate why the oldest ocean floor is only 200 million years old, despite Earth being more than 4,500 million years old. Journey through time and discover how Earth first got its water, what might have happened to the water on Mars and Venus, and how oceans shape our climate and life on our "blue planet." Explore underwater volcanoes, magnetic stripes on the seafloor, and what clues we've been left from the most ancient oceans.

This isn't just another science book; it's a beautifully illustrated adventure that encourages young readers to put on their detective hats and explore the "why" behind the world around them. It's a celebration of science as a quest for knowledge, filled with mysteries waiting to be solved.
