Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then becomes heavy enough to fall under gravity. Rain is the major component of the water cycle and is also responsible for depositing most of the fresh water on earth. There are three different ways of turning moist air into the cloud so that it rains or snows. Rain forms occur when the warm moist air cools and condensation occurs. Since warm air can hold more water than cool air when the warmer air is cooled the moisture condenses to a liquid and it rains. The water vapor in the air is condensed onto tiny pieces of dust and collected together to create the cloud. Due to heavy rain, the water level rises rapidly. The speed of the rainfall is influenced by the speed of the wind.
How does rain form?
Rain is the liquid water in the form of droplets that have condensed from atmospheric water vapor and then becomes heavy enough to fall under gravity. The vapor rises in the atmosphere and there it cools down and forms tiny water droplets through something called condensation. If the cloud droplet is dense enough to form droplets greater than diameter through the process, the droplets survive the fall through the air below the cloud, despite evaporation and reach the ground as rain. The oceans are the chief source of rain, but lakes and rivers also contribute to it. The Sun’s heat evaporates the water. It remains in the atmosphere as an invisible vapor until it condenses, first into clouds and then into raindrops.
Rain Cycle tanks can make an important contribution towards reducing the demand for mains water. Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain. It is economical and efficient water system, recycling all your rainwater that is captured off your homes roof for clean, clear water. Rain Cycle tanks can make an important contribution towards reducing the demand for mains water.
Why is rain important?
The rain is the simple form of evaporation, condensation, and precipitation. When the water becomes warm enough, it evaporates as vapor into the air. Rain and other forms of precipitation occur when the warm moist air cools and condensation takes place. As warm air can hold more water than cool air when the warmer air is cooled the moisture condenses to a liquid. Rain is the most important part of the earth. We require rain for the hydrated human body, plants to grow and everything is dependent on water. Rainwater fills streams, rivers, and lakes. Rain brings us the water we need. But in many places in the world even where you live, rain has become a menace. Because of pollution in the air, acid gases from factories, cars, and homes, the rain is becoming dangerous for the life of every.
Facts about rains:
- Rain falls from clouds in the sky in the form of water droplets, this is called precipitation.
- Water can also fall from the sky in the form of hail, sleet or snow.
- Rain is an important part of the water cycle. Learn how it works with our page explaining the water cycle for kids.
- Heavy rain can cause flooding and landslides.
- Rain allows us to create electricity through hydropower.
- Plants need water in order to survive, they receive much of this water from rain.
- Forests that experience high levels of rainfall are called rain forests.
- Weather radar is used to detect and monitor rain.
