DK People & Places: North America
North America is a continent of enormous diversity, with vast mountain ranges, huge, flat, grassy plains, hot deserts, and frozen ice caps. In the south lie the tropical islands of the Caribbean and the rainforests of Central America. To the far north, a polar ice cap 2 miles (3 km) thick covers most of Greenland. Most North Americans live in the large cities on the east and west coasts. The Great Plains and deserts west of the Mississippi River are sparsely populated, as are the forests and frozen wastes of northern Canada and Alaska.
