Publisher's Synopsis
"Beaches are full of small, grainy rocks called sand. They are made of different kinds of rocks, minerals, and even shells! But how did all that sand get there? Learn all about rockin' sand, including how it forms, how it travels from one place to another, and more. A final science lab activity engages young readers to get creative with what they've learned. It's a rockin' good time on Earth!"--.
