Which outcome on vegetation distribution results from the rain shadow effect?

💡 Explanation

When air rises over a mountain range, adiabatic cooling causes precipitation primarily on the windward side, because moisture condenses; subsequently dry air descends on the leeward side, creating arid conditions due to reduced precipitation. Therefore arid conditions occur on the leeward sides, rather than increased diversity or uniform rainfall which necessitate wetter conditions.
