Why do most people in the Sahara tend to live along the Nile River or the Mediterranean coast?
A.
because of the lack of available water resources in the region
B.
because most of the region's population works in the mining industry
C.
because the thick vegetation in the inland areas of the region limits development
D.
because there is no way to conduct trade in the region except via waterways
A. because of the lack of available water resources in the region
The correct answer is A.
Most people in the Sahara tend to live along the Nile River or the Mediterranean coast because of the lack of available water resources in the region. The Sahara Desert is one of the driest places on Earth, with very limited water sources. The Nile River provides a steady water supply that sustains agriculture and supports human settlements along its banks. Similarly, the Mediterranean coast offers access to the sea, which provides additional water resources, as well as opportunities for trade and transportation. The other options (B, C, and D) are not accurate in this context.
