The troposphere is the lowest layer of the Earth's atmosphere and extends from the Earth's surface to an altitude of about 7-20 km depending on the location. It contains a significant amount of water vapour and clouds. The amount of water vapour in the air can vary depending on the temperature and pressure, with warm and humid regions having more water vapour than cool and dry regions. The presence of water vapour in the troposphere is essential for the formation of clouds and precipitation. As warm air rises and cools, it loses its ability to hold moisture, leading to the formation of clouds. The water droplets in clouds can then combine and grow to form precipitation, which falls to the surface as rain, snow, sleet or hail.
