B. The rapid increase in population is due to a high death rate.
C. The rapid increase in population is due to a high rate of urbanization.
D. The rapid increase in population is due to a high rate of immigration.
Question 8

A. Poor infrastructure and maintenance of oil pipelines
B. Inadequate regulation and enforcement of environmental laws
C. High population density and urbanization
D. Climate change and sea-level rise
Question 9

A. Internal
B. External
C. Biological
D. Chemical
Question 13
The Earth's rotation causes the Coriolis effect, which in turn affects the formation of weather patterns. Which of the following best describes the Coriolis effect?
A. A deflection of moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
B. A deflection of moving objects to the left in the Northern Hemisphere and to the right in the Southern Hemisphere.
C. A deflection of moving objects towards the equator.
D. A deflection of moving objects towards the poles.
Question 14
The Niger Delta region of Nigeria is characterized by a complex network of rivers and creeks. What is the primary reason for this complex network?
A. The Niger Delta region is a low-lying area with a gentle slope, allowing rivers to flow easily and create a complex network.
B. The Niger Delta region has a high rainfall, causing rivers to overflow and create a complex network.
C. The Niger Delta region has a high population density, leading to deforestation and soil erosion, which in turn creates a complex network of rivers and creeks.
D. The Niger Delta region has a unique geology, with a combination of sand, clay, and silt, which allows rivers to flow easily and create a complex network.
Question 15
