Chapter 1 : The Geography of the Americas
|
Geographers organize the study of the earth and its people around
five themes: location, place, human/environment interaction,
movement, and region. They also enlist the help of various tools.
One of the more important tools is a globe, which shows the
earth in its true shape as a sphere. A map, another tool of
geography, is a representation of the earth or any part of the
universe on a flat surface. Some maps in this book are special-purpose
maps; they give information on specific topics, such as physical
regions, climate, or human activities.
The eight major physical regions of the United States are
the Hawaiian Islands, the Pacific Coast, the Intermountain
region, the Rocky Mountains, the Interior Plains, the Canadian
Shield, the Appalachian Mountains, and the Coastal Plains.
The nation's largest climate regions include the highland,
steppe, humid continental, and humid subtropical.
