Question

what is the orographic/rain shadow effect? what does it cause? what is windward and leeward?

Explanation:

The orographic/rain - shadow effect occurs when moist air is forced to rise over a mountain range. As the air rises, it cools and condenses, causing precipitation on the windward side. On the leeward side, the air descends, warms, and has low humidity, creating a rain - shadow area with less precipitation. The windward side is the side of the mountain facing the prevailing wind, where moisture condenses and rain falls. The leeward side is the side sheltered from the wind, which is drier due to the rain - shadow effect.

Answer:

The orographic/rain - shadow effect is when moist air rises over a mountain, causing precipitation on the windward side and a drier area on the leeward side. It causes differences in precipitation between the windward and leeward sides of a mountain range. The windward side is the side facing the prevailing wind where rain occurs, and the leeward side is the sheltered, drier side.
