Description
The perfect complement for any lesson on weathering and erosion, Grand Canyon offers a day-in-the-life glimpse at one of the Natural Wonders of the World. Even as coyotes hunt for food along the chasm’s rim, pack mules carry tourists along the harrowing ten-mile trail to the Colorado riverbed, and wildflowers grow, the slow forces of nature continue to reshape the layers of rock as they have for hundreds of millions of years. The book also includes a timeline and a graphic breakdown of the layers of rock by age.
