Correct Option: D. The land is liable to flood
Detailed Explanation:
-
Understanding the Geography: The Cross River is located in southeastern Nigeria and flows through a region characterized by a variety of landscapes, including plains. The area to the east of the Cross River is known for its low-lying topography, which makes it susceptible to flooding, especially during the rainy season.
-
Flooding and Its Impacts: Flooding can significantly affect human habitation and agricultural activities. When land is prone to flooding, it becomes less suitable for permanent settlement because:
- Risk to Life and Property: Frequent floods can endanger lives and damage homes, making it a risky place to live.
- Agricultural Challenges: Flooded land can lead to crop destruction, making farming unviable. Farmers are less likely to invest in land that may be submerged regularly.
-
Infrastructure Issues: Building infrastructure such as roads, schools, and hospitals becomes challenging in flood-prone areas, leading to a lack of essential services.
-
Why Other Options Are Weaker:
-
Option A: It is covered by dense, impenetrable rain forests: While dense rainforests can make areas difficult to access, they do not inherently prevent habitation. Many regions with rainforests are inhabited, as people adapt to living in such environments. Additionally, the presence of rainforests can provide resources like timber and non-timber forest products.
-
Option B: The land is not fertile enough to encourage farming: Fertility is an important factor for habitation, but it is not the primary reason for the lack of population in this specific area. Even if the land were less fertile, it could still be inhabited if other conditions (like flooding) were not a concern. Moreover, areas with less fertile land can still support some forms of agriculture or alternative livelihoods.
-
Option C: The Cross River is not navigable in this area: While navigability can affect transportation and trade, it does not directly correlate with the habitability of an area. People can still live in regions that are not easily accessible by water, especially if other factors (like flooding) are more significant deterrents.
-
Common Pitfalls:
- Students may confuse the effects of dense vegetation with flooding. While both can limit habitation, flooding has a more direct and immediate impact on safety and agriculture.
-
Misunderstanding the relationship between land fertility and habitation can lead to incorrect conclusions. Fertile land can be uninhabited if it is frequently flooded.
-
Revision Summary:
- The area east of the Cross River is largely uninhabited due to its susceptibility to flooding.
- Flooding poses risks to life, property, and agriculture, discouraging settlement.
- Other factors like dense rainforests, land fertility, and navigability are less significant in this context.
- Understanding the geographical and environmental factors is crucial for analyzing human habitation patterns.
