Which effect causes increased desertification on rain shadow sides of mountain chains?

💡 Explanation

Orographic uplift causes air to rise and cool, resulting in precipitation on one side. This rain shadow effect reduces moisture on the leeward side because air descends and warms, therefore increasing arid conditions, rather than promoting precipitation.
