Step-by-step explanation:
The term used to identify the land on the side of a mountain or hill that receives little precipitation due to lack of moist air is Option 1: Rain shadow. This phenomenon, known as the rain shadow effect, occurs when prevailing winds carrying moisture rise up a mountainside, causing the air to cool and condense, resulting in precipitation on the windward side. As the dried air descends down the leeward side of the mountain range, it creates arid climate conditions with little precipitation.
