Water - Lakes Lake Titicaca

Water - Rivers Amazon River

2nd largest river in the world

Carries more water than any other river in the world

Contains 20% of all fresh water in the world

Serves as a major trade route inland and creates fertile land

Water - Rivers Negro River

Tributary of the Amazon

Largest black water river in the world

Deep, slow-moving channel that flows through forested swamps and wetlands. The color results from the leaching of tannins from the decaying leaves of adjoining vegetation.

Climate Varies greatly

because of the size of the continent (8 zones) Below 0º in the

Andes and over 80º in the Amazon Basin

Receives over 118” of rain in the Amazon Basin each year

Most of South America has a tropical climate

Valuable Venezuela Location, climate and natural resources affect

where people live and work. Physical Features . . .

Coastline gives them easy access to trade w Mountains, grassy plains & tropical jungles

Climate in Venezuela . . . Hot and humid – just north of the equator Cooler in the Andes Mountains Rainy

Major natural resource . . . Oil

Page 18: South America Physical Geography Land - Desert Atacama Desert Atacama Desert Driest non-Arctic desert in the world Driest non-Arctic desert in the world.

Where do people choose to live?

Along the coast of the Caribbean Sea and nearby mountain valleys

Mostly urban areas – 88%

Many people work in the rich oil industry.

Large middle class – but also large amounts of poverty

Environmental Issues Oil-related pollution – Venezuela

Water pollution along both coasts and Lake Maracaibo

Severe deforestation, oil spills and air pollution

Oil spills have hurt the fishing industry and closed tourist resorts

Oil is main source of income, so people are motivated to keep drilling, producing, and burning oil…and polluting.

I’ll Trade with You! Venezuela . . . .

Oil products are the government’s main source of revenue

Major trading partners are its neighbors USA, Brazil and Colombia USA provides much of Venezuela’s food

imports since agriculture isn’t a strong industry there.

Amazon Rainforest used to be sparsely populated, BUT . . .
