Unit 8 Africa

Which Africa physical feature is pictured:

• Nile River

• Great Rift Valley

• Mt. Kilimanjaro

• Lake Victoria

How is land impacted by north Africa's climate?

• The soil is protected by a thick layer of grass

• The soil is enriched by the heavy rainfall

• The soil is at risk of becoming unusable due to desertification

• The land is mostly sandy due to the Atlantic ocean's wind

How does an increase in population affect access to water in Africa?

• Increases in population do not matter because many African countries use desalination (taking salt out of saltwater)

• An increase in population requires an increased need of water

• An increase in population causes a decreased need for water

• An increase in population leads to an increase in water due to moisture farming

What environmental issue do the pictures best show?

• Water Pollution

• Unequal access to water

• Over-fishing in Africa

• Conflicts over water use

How does water pollution impact the development of Africa?

• It decreases the rate of development because it takes large amounts of time to clean the water

• It increases development because Africans need to find new ways to de-pollute the water supply

• It slows the development because it denies Africans their basic needs

• It increases the development of Africa because other countries offer Africas help

How does deforestation impact the soil in Africa?

• The soil becomes unusable because the tree roots tear out too much of the soil on removal

• It helps the soil because the trees take away key nutrients that keeps it healthy

• It hurts the soil because the trees provide water which keeps the soil fertile

• It causes erosion and desertification

Which of the following is NOT an environmental issue of Africa?

• nuclear waste leakage

• deforestation

• air pollution

• water pollution

What two regions of Africa are MOST at risk for deforestation and desertification?

• Sahara and Sahel

• Sahel and Savanna

• Sahel and Tropical Rainforest

• Sahara and Tropical Rainforest

Which of the following is a cause of desertification?

• Allowing re-growth of grasses and other vegetation

• Allowing animals to overgraze grasses and other vegetation

• Growing trees

• Desalination

Desertification is a major problem for 1/3 of the African continent. What is desertification?

• The process of turning a desert into grasslands or farmlands.

• The process of polluting all fresh water sources until they dry up.

• the process by which fertile land becomes desert

• The process of destroying trees and other plants.
