Section 2-4

The rain forests of Latin America are the source of many medicines. For example, the poisonous bark of certain curare plants is used to treat such diseases as multiple sclerosis and other muscular disorders, and as a surgical anesthetic. Scientists use the chemical structures of rain forest plants as models from which they can synthesize drug compounds. Rain forest plants also aid in research. Some plant compounds show scientists how cancer cells grow, for example.

Section 2-5

Climate and Vegetation RegionsMost of Latin America lies between the Tropic of Cancer and the Tropic of Capricorn; thus, much of its area has a tropical climate. However, there is a great variety of climates in the region.

• Tropical Regions Mexico, eastern central America, some Caribbean islands, and such parts of South America as the Amazon Basin have a tropical rain forest climate and vegetation, with hot temperatures and abundant rainfall occurring year-round.


(pages 199–202)(pages 199–202)

Section 2-6

• The Rain Forest The Amazon Basin, with the earth’s largest rain forest, covers one-third of South America and has trees that form a dense canopy that soars as high as 130 feet over the forest floor.

• Tropical Savanna In the tropical savanna climate typical of the coast of southwestern Mexico, most Caribbean islands, and north-central South America, the grasslands have hot temperatures, abundant rainfall, and a dry season lasting several months.

Climate and Vegetation Regions (cont.)


(pages 199–202)(pages 199–202)

Section 2-7

• The Humid Subtropics In the humid subtropical climate of southeastern South America, the winters are short and mild, and the summers are long, hot, and humid.


(pages 199–202)(pages 199–202)

Section 2-8

• Desert and Steppe Areas Parts of northern Mexico and the southwestern region of South America have desert climates and vegetation; in Chile the rain shadow effect of the Andes has produced the dry, arid Atacama Desert, whereas other areas have a steppe climate, with hot summers, cool winters, and light rainfall.

Section 2-10

What kinds of vegetation might be found in rain forest areas of Latin America?

Hardwood trees, palms, tree ferns, and bamboo might be found in the rain forests of Latin America.




(pages 199–202)(pages 199–202)

Section 2-11

Elevation and Climate• The climates of Latin America depend

more on elevation than on distance from the Equator.

• The tierra caliente lies between sea level and 2,500 feet and has average annual temperatures from 68F to 91F. The main crops include bananas, sugar, rice, and cacao.


(pages 202–203)(pages 202–203)

Section 2-12

• The tierra templada lies between 2,500 and 6,500 feet and has average daily temperatures between 60F and 72F. Coffee and corn are the main crops.

• In the tierra fría, frosts are common in the winter months. Potatoes and barley grow at these elevations.

Elevation and Climate (cont.)


(pages 202–203)(pages 202–203)

Section 2-13

Why do you think most Latin Americans live in the tropical zones rather than high in the Andes Mountains?

It is easier to survive in a tropical climate. People can grow food, and they will not suffer from severe winters. High in the mountains, the temperatures are much colder, and farming is much more difficult. Travel, communications, and access to services such as education, cultural events, and health care are all more difficult.

Section 2-15

Critical Thinking

Making Inferences Why might some Latin Americans live in areas in which climate and agriculture are unfavorable?

Possible answer: Some Latin Americans might live in these areas because of tradition and natural resources (for example, minerals and timber) that can support them economically.



Section 2-16

Determining Cause and Effect How does elevation affect climate and vegetation in Latin America?



Critical Thinking

Possible answer: Higher elevations have cooler temperatures and less varied vegetation.

A. The average temperature and amount of rainfall are about the same.

B. It is hotter and drier in November.

C. The average temperature is about the same, but it is wetter in

November.

D. The amount of rainfall is about the same, but it is hotter in

November.



Test-Taking Tip Study the information shown on the climograph for average temperature and monthly precipitation. Then look carefully at the data for the months of April and November. Compare the amount of precipitation for the two months. As a result, you will be able to eliminate some of the statements.

GeoFact 1

Many nonvolcanic Caribbean islands are partially or completely composed of coral, the hard outer skeletons of tiny marine animals. The world’s second-longest coral reef–a 75-mile (121km) stretch popular with tourists and ecologists–lies off the coast of Belize in Central America.

Interdisciplinary Connection 2

Biology There are many distinct varieties of ants in the Amazon rain forest. One variety, army ants, of which there are about 200 species, does not build permanent nests. Millions of them travel together in columns at speeds of up to 65 feet (20 m) per hour. A swarm can destroy crops as well as small animals.

Skill Builder 1

Identifying cause-and-effect relationships involves considering how and why an event occurred. A cause is the action or situation that leads to the event. An effect is the result or consequence of an action or situation.

Identifying Cause-and-Effect Relationships

Skill Builder 2

Learning the SkillCause-and-effect relationships may be simple or complex. Several causes can produce a single effect. For example, a forest fire may be caused by a series of events or conditions. Hot weather and lack of rain make grass and wood dry and flammable. The day the fire started might have been windy, and the wind might have blown sparks from a camper’s fire into some dry grass.


Skill Builder 3

Similarly, one event can produce several effects. A large forest fire can destroy animal habitats. It can also suddenly reduce plant cover, making the land more susceptible to erosion from wind and rain. A large fire can also be expensive to fight and damaging to homes and businesses, harming the economy of an entire region.

Learning the Skill


Sometimes one event causes several other events in a chain reaction. A traffic accident on a highway may cause another accident, which causes another accident, and so on. Strings of causal relationships are called cause-and-effect chains.


Skill Builder 4

Follow these steps to identify cause-and-effect relationships:

• Ask questions about why events occur. • Identify the outcomes of events.

• Look for clues that indicate a cause-and-effect relationship. Words and phrases such as because, as a result of, brought about, as a consequence, therefore, and thus can help you identify cause-and-effect relationships.

Learning the Skill
