The Grand Canyon in Arizona occupies about triple the area of the world’s ten smallest countries. Land used for farmland worldwide would fill an area about 10,000 times that of the Grand Canyon.

Using everyday experiences and extensive color illustrations, Arcand and Watzke explain how orders of magnitude enable us to make sense of the world around us.
