Question
How does orographic precipitation form in coastal areas? Warm air is forced upward by cool, heavier air. Moist winds are forced upward by high landforms. Hot, humid air rises from the earth’s surface and cools. Dry, hot air warms the area behind inland mountains.

Orographic precipitation occurs when moist air encounters a mountain range or high landforms. Here's how it forms, particularly in coastal areas:
1. **Moist Winds**: Coastal regions often have strong winds that blow in from the ocean, carrying moisture. When these moist air masses reach a mountain range, they are forced to rise.
2. **Forced Uplift**: As the moist air rises over the mountains, it encounters cooler temperatures at higher altitudes. The cooling of the air causes the moisture to condense, forming clouds.
3. **Precipitation**: As the condensation continues, droplets of water eventually become heavy enough to fall as precipitation (rain, snow, etc.) on the windward side of the mountain.
4. **Rain Shadow Effect**: After the air descends on the leeward side of the mountain, it warms up. This warming reduces humidity and results in much drier conditions, creating what is known as a rain shadow.
In summary, the correct statement from your options regarding orographic precipitation is: "Moist winds are forced upward by high landforms." This describes the primary mechanism by which orographic precipitation occurs in coastal areas.
