Which climatic element explains why higher elevations are cooler and drier?

Which climatic element explains why higher elevations are cooler and drier?

• A. Elevation (Altitude)
• B. Latitude
• C. Proximity to Water
• D. Ocean Currents

Answer: (A)

Raising elevation brings you into thinner, less dense air with lower pressure. As air rises, it expands and cools—a process called adiabatic cooling. Cooler air holds less water vapor, so the moisture content decreases and the air feels drier. This combination of cooler temperatures and lower humidity is why higher elevations are both cooler and drier than low-lying areas. Factors like proximity to water or ocean currents influence climate in other ways, but the direct effect of elevation itself explains the cooler, drier conditions.
