Answer: The rainfall occurs when the masses of air pushed by wind are forced up by large mountains
Notes: The correct answer is that orographic rainfall occurs when moist air is forced to rise over large mountains, leading to cooling and condensation. This type of rainfall is common in India, particularly in the Western Ghats and the Himalayas. The windward side of the mountains receives heavy rainfall, while the leeward side, or rain shadow area, experiences importantly less precipitation. This phenomenon is crucial for understanding regional climates and agriculture in mountainous areas.
