As altitude increases, air pressure and density decrease. The thinner air at higher altitudes cannot retain heat efficiently, making temperatures drop. That’s why mountain regions are cooler than plains. Altitude significantly influences local climate and supports snow in high elevations.

Class 7 Social Science Chapter 3 Climates of India question answer
Altitude directly affects both air pressure and temperature. Higher altitudes have lower air pressure and thinner air, which holds less heat. This results in cooler temperatures. For every 1000 meters climbed, temperature drops by about 6.5°C. That’s why hill stations are cooler than surrounding plains. Mountains like the Himalayas remain snow-covered due to their elevation. Thus, altitude influences weather conditions, vegetation and human settlements, making it a key factor in determining regional climates and lifestyles.
