Section 2:
Climate and Vegetation
Visual Summary
You have seen stories in
the news about the
importance of the
environment and
conservation in the United
States and Canada.
Studying the physical
geography will explain the
importance of the region’s
natural features and how
the environment affects
people in the region.
Section 1:
The Land
Changes occur in the
use, distribution, and
importance of natural
resources. A variety of
landforms, water systems,
and natural resources
have played an important
and changing role in the
development of the United
States and Canada.
Section 2: Climate and
Vegetation
Geographers organize
Earth into regions that
share common
characteristics. Location
and landforms affect
climate regions and natural
vegetation of the United
States and Canada.
The Land
This section discusses the
landforms, water systems, and
natural resources that play an
important and changing role in
the development of the United
States and Canada.

Southern Climates
Location near the coast, as well as
prevailing wind patterns, results in the warm
and wet climates and warm and dry climates
of the southern United States.

States:
– Warm and wet climates
• Subtropical
• Tropical

Northern Climates
Variations in climate and vegetation in most
of the United States and Canada are the
result of the combined effects of latitude,
elevation, ocean currents, and rainfall.
●
