Due to the difference in sunlight and precipitation on the leeward and windward side of a mountain range, the plant and animal species that can survive in each zone may differ considerably.

On the windward side of a mountain range, precipitation tends to be copious as the water vapour in most air condenses to form rain clouds as it rises up the slopes of the range.
