Its concentration in the atmosphere varies greatly but is generally highest near the Earth&#8217;s surface due to evaporation from water bodies and plants. As altitude increases, temperature and pressure decrease, limiting the amount of water vapour the air can hold (dew point decreases). Therefore, the amount of water vapour typically decreases significantly with altitude. This statement is correct.<br \/>\nStatement 2: The amount of water vapour the air can hold is strongly dependent on temperature. Warmer air can hold much more water vapour than cold air. The poles are very cold regions. Consequently, the absolute amount and percentage of water vapour in the atmosphere are generally lowest at the poles and highest in warm, humid tropical and equatorial regions.
