Clouds rain because the water vapor in the atmosphere condenses back into liquid form, forming droplets or ice crystals that become too heavy to remain suspended in the air. These droplets or ice crystals come together and fall towards the ground as precipitation, such as rain or snow. The process of condensation occurs when the air temperature cools down and reaches the dew point, which is the temperature at which the air becomes saturated with water vapor and can no longer hold it in the gaseous form. Different factors like temperature, air pressure, and humidity can influence the rain formation process.
