• Most people living in the Sahara live in highly dense urban centers.

• Most people living in the Sahara work in the logging industry.

• Most people living in the Sahara work in the mining industry.

In 2010, an extreme drought occurred in the Sahel region in West Africa. Which of the following BEST explains how this led to a scarcity of food in the region?

• Because the weather was so wet, the soil in the region became too muddy to grow food.

• Because the wind was so harsh, animals in the region on which people relied for food went into hiding.

• Because the region received little rainfall, people were unable to grow the food they needed.

• Because the temperature in the region was high, people could not travel to get the food they needed.

Why do most people in the Sahara tend to live along the Nile River or the Mediterranean coast?

• because there is no way to conduct trade in the region except via waterways

• because the thick vegetation in the inland areas of the region limits development

• because most of the region's population works in the mining industry

• because of the lack of available water resources in the region

The African savanna gets an average of 30–50 inches of rainfall each year. How does this affect the people who live there?

• Families are typically very large, so there are always enough workers to search for water to bring back for cooking, cleaning, and farming.

• Population changes dramatically over the course of the year, rising in the wet season and declining in the dry season.

• People can stay in one spot to raise crops and livestock because they do not constantly have to search for water.

• People must live in flood resistant homes built on stilts to protect them from the annual rains.
