26. Which of the following is an accurate description of population patterns on the continent of Africa?
Answer: A
Population is concentrated south of the Sahara in areas with access to water.
Population patterns in Africa demonstrate that a significant concentration exists in regions south of the Sahara, particularly where water resources are available. This trend reflects the necessity of water for both agriculture and habitation.
A) Population is concentrated south of the Sahara in areas with access to water.
This statement accurately reflects the demographic trends in Africa, as population density increases in regions with reliable water sources. Areas such as the Nile Valley and coastal regions benefit from these resources, leading to higher population concentrations.
B) Population is concentrated in northern central regions around major cities.
While there are major cities in northern central Africa, this statement does not fully capture the broader population patterns across the continent. The majority of Africa's population is not primarily found in these regions, making this option misleading.
C) Population is sparse in East Africa and dense along the southwestern coast.
This description inaccurately represents population distribution, as East Africa has significant urban centers and areas of population density, particularly in cities like Nairobi and Dar es Salaam. In contrast, the southwestern coast exhibits varying population densities, making this assertion incorrect.
D) Population is rapidly shifting north in response to new irrigation techniques.
There is no substantial evidence suggesting a rapid northward shift in population driven by irrigation techniques. Instead, population growth in Africa tends to be influenced by factors such as urbanization and resource availability rather than a significant migration northward.
Conclusion
The correct answer highlights the importance of water availability in shaping population patterns in Africa, particularly south of the Sahara. The other options fail to accurately reflect the diverse and complex demographic landscape of the continent, making A the only option that accurately describes the population distribution.
