Africa Geography Summative Review

In sub-Saharan Africa, less than 50% of the population has access to safe drinking water because of environmental pollution. How has this shortage of safe drinking water most likely affected development in sub-Saharan Africa?

• It has slowed economic growth.

• It has increased the size of the Sahara.

• It has increased population growth.

• It has slowed deforestation of the rainforest.

What effect does poor soil and deforestation have on land in Africa?

• Land is excellent for archaeological dig sites.

• Land becomes useless for agriculture.

• Land becomes part of national park systems.

• Land becomes a better place to raise a family.

In the Sahel, overgrazing and drought have resulted in a decrease in the steppe region and increase of the Sahara. What is this process called?

• Deforestation

• Desertification

• Unequal Distribution

• Environmental Pollution

In which of the following regions in Africa would you most likely find someone working in the logging industry?

• The Sahara

• The Sahel

• The Savannah

• The Tropical Rainforest

Where is farming possible in the Sahara?

• in the tropical rainforest areas

• near the Nile River and scattered oases

• in the large grassland areas

• near the southern tip of Africa

If African's living in the Sahel know that their nomadic and semi-nomadic herding lifestyles are causing desertification, why do they keep doing it?

• They need to feed their families and it is the only economic opportunity they have.

• They are more concerned with becoming wealthy than they are with protecting the environment.

• They farm land is so good in the Sahel that they get bored and look for something else to do.

• They believe spreading the desert will eventually result in more arable land in the region.

Why don't the people that live in the Savannah work in the logging industry?

• There are too many trees there to support logging.

• The soil in the Savannah is the worst soil in Africa.

• There are not enough trees there for major logging companies.

• The Savannah has no vegetation at all.

Where in Africa would you expect to find the highest population density?

• along rivers, near the coast, and in the Savannah

• along rivers, near the coast, and in the Saharh

• in the Sahel , along the coast, and in the Tropical Rainforest

• near the coast, in the Savannah, and in the Sahel

Which of the following is most likely the reason for the thin line of densely populated area in the northeastern corner of Africa?

• The Niger River

• Lake Victoria

• The Atlas Mountians

• The Nile River

Which of the following would MOST LIKELY be the cause of the relatively light population density in western central Africa?

• Lack of water makes farming difficult.

• The spread of the desert into the region is causing people to move away.

• Dense forests make it more difficult to build cities and infrastructure.

• Large grass covered plains make it more difficult to herd animals.
