Ready to dig to the other side of the earth? Not so fast! In this BrainPOP movie, Tim and Moby introduce you to the composition and structure of our home planet. Find out about the three layers of the earth, the elements thought to make up those layers, and what’s really at the center (hint: it’s not gooey). You’ll also learn how scientists study earthquake waves to figure out what exactly that lies beneath our little feet! Pick up a shovel if you must, but don’t forget to stop for dinner!
