Rain

Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then precipitated that is become heavy enough to fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystems as well as water for hydroelectric power plants and crop irrigation. Rain is the drops of water that fall on the earth from the cloud. Rainfall is defined as fall of innumerable drops of water rain at a time on the earth surface. Water from seas’ ocean’ river’ lakes’ canals’ ponds etc. gets vaporized due to the heat of the sun. This vapor rises up and comes in contact with cold air and condenses in the form of cloud. When this cloud is cooled further it cannot float in space and falls down on the earth surface as rain by the gravitational attraction of the earth. The rainy season or monsoon season is the time of year when most of a region's average annual rainfall occurs. It usually lasts one or more months. The term green season is also sometimes used as a euphemism by tourist authorities. Rain brings a multitude of benefits to the earth including watering wild plants and crops humidifying the air creating streams and rivers replenishing the water table and creating healthy negative ions. Perhaps the most important benefit of rain is its redistribution of fresh water in the water cycle. Rain is wonderful but in life too much of a good thing can be bad. Rain can potentially ruin delay prolong any outdoor event. Rain can be an inconvenience to those who left the house without appropriate clothing raincoat rain boots etc have their hair done nicely or are prone to frizzy hair in humid conditions or left something outdoors drying clothes left car window down etc exposed to the rain. Rain can cause floods which as Matthew stated can cause property damage bodily injury or death potentially for large amounts of people. Rain can be a part of storms storms and rain frighten some people. There are 3 main types of rainfall relief frontal and convectional. Describe each and give conditions when the occur. 10 marks Relief rainfall occurs when air has been blown over the sea and is then forced up over an area of high land. Rainwater is good for washing your hair because it is a soft water that is neutral in pH’ free from disinfection by products salts minerals and other unnatural materials. Tap water which is harder in comparison does not wash hair as well because it makes lathering and rinsing more difficult. Water from the roof may not be safe to drink but where safe rainwater collection systems have been put in place water collected may be drunk without being boiled. All one has to do is to leave it to settle remove pollutants before drinking Kahwah says. Before falling to the ground rain water picked up many contaminants present in the air. Drinking rain water near chemical plants or near the plumes of power plants, paper mills etc is not safe to drink but people living far from such places can drink rain water. They should make sure to boil rain water first. Rain water is considered the purest form of water. Impurities and salts present in water on earth are left behind during vaporisation by the sun. The rain water we receive on earth is not necessarily pure as it brings down impurities and particles present in the atmosphere along with it. The source of almost all fresh water is precipitation from the atmosphere in the form of mist rain and snow. Fresh water falling as mist rain or snow contains materials dissolved from the atmosphere and material from the sea and land over which the rain bearing clouds have traveled.
