Reading Level: 4th − 5th Grade

Did you know that Montana's Grasshopper Glacier is filled with millions of frozen locusts that got caught in a storm more than 300 million years ago? Or that gneiss is one of the world's oldest rock forms? One sample from Canada is more than FOUR BILLION years old! In this latest single-subject Weird But True! book, readers will have a blast discovering that there's a lot more to rocks and minerals than meets the eye.

This book is perfect for budding geologists or any kid who likes to get to the bottom of things, such as how volcanoes work or the difference between fool's gold and actual gold. Prepare to be dazzled by our rockin' world!

Also includes:

  • Profiles of "Rock Stars" (what we like to call famous geologists!)
  • Breathtaking images of awesome rock formations in national parks from around the globe (from Arches National Park to Tsingy de Bemaraha National Park in Madagascar and more!)
  • Fascinating stats and facts!
