Earth

"Earth is a special planet! This small, rocky planet is the only one known to sustain life. It's also the only planet in our solar system with just one moon! But just because humans call Earth home, that doesn't mean we know everything about it. Scientists continue to learn about Earth using orbiting spacecraft to study it from above. Using clear, concise language, this book explores all the marvelous, mysterious wonders of Earth"-- Provided by publisher.
