Our eyes help us look at the world, but there are many things we cannot see. Atoms are the building blocks of everything in the universe, from planets and stars to the cells that make up plants, animals, and the human body. Atoms are invisible because they are so small, but bigger things can be invisible, too. Ancient artifacts and buried bones are hidden under the ground, while invisible forces such as earthquakes and winds shape life on Earth. This book explores the invisible world of planet Earth. See our unseen world through satellite images taken hundreds of miles above Earth's surface. Learn about the invisible forces that help to shape the land. Take a close look at some of the extraordinary creatures hidden in the ocean depths. Book jacket.
