Which mechanism causes the aridity observed on the leeward side of mountain ranges bordering major river streams?

💡 Explanation

When moist air arrives at mountains, the rain shadow effect occurs because air rises and cools, causing condensation and precipitation on the windward side while the leeward side receives descending, dry air from the ascending streams. Therefore aridity results, rather than other conditions which require contrasting air flow or thermal dynamics.
