How does elevation affect climate?

• A. Elevation has no impact on climate.
• B. Elevation warms the air.
• C. As elevation increases, air cools.
• D. Elevation only affects humidity.

Answer: (C)

When we look at elevation's effect on climate, the main idea is that temperature drops as you go higher. Air pressure falls with height, so rising air expands and loses heat. In the lower atmosphere, the typical lapse rate is about 6.5°C per 1,000 metres. That means higher places are cooler overall, with shorter growing seasons and often snow at higher elevations even when lower areas are warmer. Cooler air also holds less moisture, influencing humidity and precipitation patterns—moist air rising over mountains cools and releases rain or snow on windward slopes, while leeward sides stay drier. So elevation truly changes both temperature and precipitation, shaping the climate of mountainous regions.
