Mountain, Boulder, Pebble, Sand

A poetic and easy to understand introduction to geology and the rock cycle. A boulder falls from a mountain and cracks into cobbles, which transforms into pebbles, then granules, then sand, and silt, until the rock that began as a mountain in the clouds is now part of a mountain the ocean where the cycle begins again. Extra nonfiction content at the back of the book gives readers a more in-depth look at how scientists classify different rock sizes. A gorgeously illustrated, perfect introduction to earth science for our youngest geologists.
