Dirt's not all that interesting—or is it? In truth, Earth's soil is one of the major reasons life on the planet can exist! In this book, readers will learn that there's far more to dirt and soil than the stuff you get on your sneakers or sweep off your front steps. Illustrations will show more about soil's origins and makeup, as well as the nutrients it provides for growing things. Projects and activities allow young geologists to put what they're learning into practice and get their hands dirty as they investigate the world beneath our feet.
