Rain is the result of water droplets gathering together in clouds and gravity causing the water droplets to fall as rain. Warm air has more water droplets than cold air.Continue Reading
Rain is part of the water cycle. Air contains invisible moisture called water vapor. This is apparent on warm, humid days.when the air is thick with water vapor. Because warm air can hold more water vapor than cooler air, when the air becomes cooler, excess water vapor is condensed out as water in the form of water droplets. These water droplets are carried up into the clouds and as the clouds become heavy, rain may fall.
Water droplets inside clouds either grow on their own or join up with other droplets to become drops. Millions of drops form in clouds and the clouds can only hold so much water before they become too heavy to hold more. Both gravity and the weight of the water play a part in a rainstorm.
When rain begins to fall, not all of it makes it to the surface. Some of it is blown around and evaporates and some ends up back in the cloud. It will continue raining as long as water continues making the clouds heavy.Learn more about Rain
Rain occurs through the process of coalescence, where a mass of water droplets gathers around cloud condensation nuclei to saturate the atmosphere and allow condensation and precipitation to take place. This process is driven by three primary lifting mechanisms that cause the upward movement of air.Full Answer >
Rain and other forms of precipitation occur when water accumulates in the clouds and falls to the ground. This occurs due to the water cycle, which continually recycles the water on Earth.Full Answer >
Rain and other forms of precipitation fall from the clouds. When warm air passes over a body of water, it causes the water to evaporate. Once the water rises high enough, it clumps with other water vapor and becomes a cloud. The air cannot hold an infinite quantity of water, so when the amount of water present in the cloud exceeds the air’s ability to hold it, the water falls in droplets as rain.Full Answer >
Precipitation forms when condensation inside clouds occurs at the level that the droplets become heavy enough to fall down to the Earth's surface. Rain, hail, freezing rain, snow and sleet are all types of precipitation that result from different conditions in the atmosphere.Full Answer >
