Which type of rainfall is caused by mountains forcing air to rise?
- Convectional
- Orographic
- Cyclonic
- Frontal
Answer: Orographic
Orographic rainfall occurs when moist air is forced to rise over a mountain barrier. As the air rises, it cools and condenses, causing precipitation on the windward side. The leeward side experiences a rain shadow effect with less rainfall. Common in Western Ghats and Himalayas.
