Question

8 using source 3, which situation best explains how physical factors affect population distribution? a russias weather in the northernmost regions allows for the population to settle along the norther border of the country. b the egyptian river valley has promoted human settlement allowing irrigation and created fertile soil for agriculture. c chiles atacama desert, one of the driest places on earth, allows for a large population to settle there because they do not have to worry about flooding. d nepal, which is above 10,000 feet above sea level, has allowed the population to increase because people are able to access transportation easily.

Explanation:

• Option A: Russia's northern regions have harsh, cold weather, so population does not settle along the northern border. Eliminate A.
• Option B: The Egyptian River (Nile) valley has fertile soil from annual flooding and supports irrigation for agriculture, which promotes human settlement. This correctly links physical factors (river valley, soil, water for irrigation) to population distribution.
• Option C: The Atacama Desert is extremely dry, lacking water for basic needs, so it cannot support a large population. The reasoning about "not worrying about flooding" is incorrect as water scarcity is the main issue. Eliminate C.
• Option D: Nepal has high altitude (above 10,000 feet in parts), which makes transportation difficult, not easy. Eliminate D.

Answer:

B. The Egyptian River valley has promoted human settlement allowing irrigation and created fertile soil for agriculture.
