Correct Option: C. Terrain to the south is less rugged Explanation of the Correct Answer:

1. Understanding Settlement Patterns: Settlements tend to develop in areas that are more accessible and suitable for human habitation. This includes considerations of terrain, climate, and resources. Rugged terrain can hinder transportation, agriculture, and infrastructure development, making it less attractive for settlements.
2. Terrain Analysis: The statement indicates that the terrain to the south is less rugged. This means that the land is likely flatter and easier to build on, which is conducive to the establishment of towns and cities. Less rugged terrain typically allows for better transportation networks (like roads and railways), easier access to resources, and more efficient agricultural practices.
3. Implications of Rugged Terrain: In contrast, rugged terrain (such as mountains or steep hills) can create barriers to movement and development. It can limit the size and accessibility of settlements, as people tend to avoid areas that are difficult to navigate. Therefore, if the south has less rugged terrain, it is more likely to support a higher density of settlements.

Why the Other Options Are Incorrect:

• Option A: Land to the north being more fertile is reserved for farming
• Explanation: While fertile land is indeed important for agriculture, it does not directly explain why there are more settlements to the south. Fertile land can support settlements, but if the terrain is rugged, it may not be developed into settlements. Thus, this option does not address the primary reason for the distribution of settlements.
• Option B: Areas to the north are liable to flooding
• Explanation: Flooding can deter settlement in specific areas, but it does not universally explain the overall pattern of more settlements to the south. If the north is prone to flooding, it might lead to fewer settlements in those specific flood-prone areas, but it does not account for the overall settlement distribution across the entire region.
• Option D: North is more prone to river blindness
• Explanation: River blindness (onchocerciasis) is a health issue related to certain environmental conditions, but it is not a primary factor influencing settlement patterns. While health concerns can affect where people choose to live, they are typically secondary to more immediate factors like terrain and accessibility. This option does not provide a strong basis for understanding why there are more settlements to the south.

Summary of Key Points:

• Settlements are more likely to develop in areas with less rugged terrain, which facilitates transportation and infrastructure.
• Rugged terrain can limit accessibility and the establishment of larger communities.
• Fertility, flooding, and health issues are important but do not directly explain the overall pattern of settlement distribution.
• Understanding the relationship between terrain and settlement patterns is crucial for geography studies.

This thorough understanding of the factors influencing settlement patterns will help you in your geography exam and in analyzing similar questions in the future.
