Glaciers, rivers, wind, and rain are a few of the elements that shape the landscape in powerful ways. They form features big and small—from grand canyons and enormous caves to smooth pebbles and fine grains of sand. Lyrical verse by Heather Ferranti Kinser introduces weathering, erosion, and deposition, and eye-catching photos provide a look at some of the world's geological marvels. Back matter gives more information about the processes that sculpt the landscape and highlights formations including Half Dome, a hoodoo, and basalt columns.
