Relief rainfall is mostly associated with

Step 1: Analyze the question The question asks which landform is mostly associated with relief (orographic) rainfall.

Step 2: Explain the concept Relief rainfall happens when moist air is forced to rise over high ground, such as mountains or plateaus:

1. Warm, moist winds (for example, from the Atlantic Ocean) blow toward a highland.
2. The air is forced upward along the windward slope.
3. As it rises, it cools, and the water vapour condenses into clouds.
4. Heavy rain falls on the windward side.
5. The air then descends on the leeward side, warming and drying. This area gets little rain and is called the rain shadow.

Step 3: Check each option

• A. Lowlands: These are flat or low-lying areas with no barrier to force air upward, so they are not typical of relief rainfall.
• B. Peneplains: These are almost flat, worn-down plains, so there is no significant obstacle to lift the air.
• C. Highlands: Mountains and plateaus force air to rise, so this is where relief rainfall occurs.
• D. Deserts: These are dry regions, usually with little rainfall.

Step 4: Answer The correct option is C. highlands.

Nigerian example: The Jos Plateau, the Obudu Plateau, and the Adamawa Highlands receive more rainfall than the surrounding lowlands because of relief rainfall.

Exam tip: Remember "Relief = Raised land." If a question says relief or orographic rainfall, think of mountains or highlands. Also remember that the windward side is wet and the leeward side is dry.
