What phenomenon occurs at the leeward slope of mountains due to Orographic Lifting?

• A. Increased precipitation
• B. Rain shadow effect
• C. High humidity levels
• D. Air stagnation

Answer: (B)

The phenomenon that occurs at the leeward slope of mountains due to Orographic Lifting is referred to as the rain shadow effect. When moist air approaches a mountain range, it is forced to rise over the peaks. As the air rises, it cools and loses moisture in the form of precipitation on the windward side of the mountain. This results in increased rainfall in that region. However, by the time the air descends on the leeward side, it has lost much of its moisture, leading to significantly drier conditions in that area. This creates a rain shadow—an area with reduced precipitation compared to the windward slopes. The rain shadow effect is a fundamental concept in understanding how geography can influence local climates.
