kannada essay on uses of rain
As we all know, the three essentials for survival are water, food, and air. The most important element of weather is water. We get water in different forms of precipitation. Rain is the most beneficial of all types of precipitation. Rain is what harvests our crops that give us food to eat. Without rain, no crops would grow and we would parish off the face of this Earth. Also, keeping our air clean is essential because we need air to breathe. Since water, food, and air are so important for our survival as human beings, I decided to do my report on factors of rain.
The Mississippi River, the Great Lakes, and countless other river, lakes, and streams make up the water cover of the United States. What few people realize, though, is that a lot of our water is stored beneath the ground. The water is held naturally in cavities called aquifers. In urban areas, water supplies are stored in holding areas called reservoirs. Everyday, Americans are using water that comes from all of these sources.
As many people are familiar with the water cycle, they fail to realize how important it really is. The water in Earth’s atmosphere condenses in the sky around small particles of dust. This procedure that is referred to as condensation is the process whereby water vapor changes to the liquid state. Then, rain falls from the clouds to the ground and makes its way into rivers, lakes, and aquifers. Eventually, almost all of the water evaporates back into the atmosphere from the sun. The demand for water is very high throughout the United States, especially where natural water resources are limited. Farmers use 140 billion gallons each day to grow crop and raise livestock. Industry needs 30 billion gallon for jobs that involve cooling.
Introduction and meaning: 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.
Causes of rain: Water from seas, ocean, river, lakes, canals, ponds etc. get 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.
How rainfall is measured? The amount of rainfall at any place is measured by an instrument called rain-gauge. Rainfall is generally measured in inches or centimeters.
Classification
Rainfall on the surface of the earth may be classified into three kinds according to the causes of origin, characteristics and nature. There are:
Convectional rainfall: Intense heating of the surface of the earth during daytime, makes the air hot that is in close contact to the earth’s surface. This hot air expands in mass, becomes lighter and rises upward. The rising mass of air progressively losses the heat in the appear layer of atmosphere where it cools up and is condensed thereby generating heavy shower often in the afternoon and evening when temperature reduces remarkably. Such a kind of rainfall found during evening and afternoon of summer season, restricted to a certain particular locality is defined as convectional rainfall. This type of rain is very common during afternoon in equatorial region.
Orographic rainfall: When flow of humid air coming from the sea is obstructed obliquely by a mountain, the air gets up sliding along the slant of the mountain and being cooled and condensed it causes rainfall on the windward slant. Such rainfall is known as Orographic Rainfall. In the state of Meghalaya such rainfall occurs at Cherapunji and Mousinram.
Cyclonic rainfall: Rainfall caused by cyclone is known as Cyclonic rainfall. Generally, when hot humid air and cold air, moving parallel to the earth surface, approach each other, the hot air rises above the cold air and causes cyclone. Mainly in temperate region such cyclone occurs.
