Section 2:
Climate and Vegetation
Visual Summary
News accounts of natural
disasters in Latin America
describe the destruction
caused by hurricanes,
earthquakes, and volcanic
eruptions. A study of the
physical geography of
Latin America will explain
the factors that make the
region vulnerable to such
natural disasters.
Section 1:
The Land
The physical
environment affects
people and their
activities. The rugged
Andes and the massive
rivers of Latin America
influence human
settlement in the region.
Section 2: Climate and
Vegetation
Physical processes
shape Earth’s surface.
Location and landforms
result in vertical climate
zones and tropical areas
in Latin America.
The Land
This section discusses the
landforms, water systems, and
natural resources of Latin
America, and how these
features have influenced human
settlement in the region.

Natural Resources
Latin America has abundant natural
resources but faces obstacles to
development.
• Some Latin American countries are among the
world’s leading producers of energy and mineral
resources.

Climate and Vegetation
Location and landforms affect
climate and vegetation regions
in Latin America, but human
activity has modified forest
cover and land use patterns.

Elevation and Climate
Differences in elevation create five diverse
climate zones in Latin America.
• The five vertical climate zones found in the highlands
of Middle America and western South America are
the:
– tierra helada and the puna
– tierra fría
– tierra templada
– tierra caliente

Climate and Vegetation Regions
Although much of Latin America is located
in the Tropics, the region has diverse
climates and vegetation.
• Tropical climates:
– Tropical wet—The Amazon Basin
– Tropical dry
Climate and Vegetation Regions (cont.)
• Midlatitude climate:
– Humid subtropical
• Dry climate:
– Desert—The Atacama Desert
– Steppe
Latin American Climate Regions
The Amazon rain forest shelters more
species of plants and animals per
square mile than anywhere on Earth.

A. Mexican Plateau
• Surrounded by
Sierra Madre
• Mild climate, good
soil, adequate
rainfall
• Has attracted
human settlement
for years
B. Caribbean Islands
• Volcanic mountains
• Part of the Central
Highlands
• Experiences
hurricanes that form
in the Atlantic Ocean
C. Oil and Natural
Gas Resources
• Important economic
resources for some
countries in the
region
• Not distributed
equally; only a few
countries benefit
D. Amazon River
• Longest river in
North and South
America
• Amazon Basin
drains into Atlantic
Ocean
• Important
transportation route
from the Atlantic into
Brazil’s interior
E. Andes
• World’s longest
mountain ranges
• Rugged terrain has
made movement
difficult
• Tectonic activity
causes earthquakes
and volcanic
eruptions
• Vertical climate
zones have
attracted human
settlement because
of cooler climates
and rich natural
resources
F. Amazon Rain Forest
• World’s largest rain
forest–covers onethird of South
America
• Trees grow close
together to form a
dense canopy
• Heavy rains occur
throughout the year
• Shelters more
species of plants and
animals per square
mile than anywhere
else on Earth
G. Paraná, Paraguay,
and Uruguay Rivers
• Provide important
commercial
transportation routes
• Provide hydroelectric
power for the area
• Form the Rio de la
Plata where rivers
flow into the Atlantic
Ocean
H. Pampas
• Plains and grassland
area provides grazing
for beef cattle
• Wheat and corn are
grown in the rich coil
of the pampas for
export around the
world.
