what is green revolution

It is the time taken by a satellite to complete one revolution around the Earth. Circumference of a circle of radius R + h is 2 p (R+h). Let T be the time period, v the velocity and h the height of the satellite above the Earth's surface. Substituting in the equation, we get ..

Green manuring is the practice of growing and ploughing in, the green crops, into the soil. It is a cheap and effective method that increases soil fertility as it can supplement farmyard and other organic manures and is more cost effective. Green manures add nitrogen ..

Simply stated, Green chemistry is the use of chemistry for preventing environment pollution in order to protect human health. It may give the impression that it is branch of chemistry involving plants, which is not true. Green chemistry may be defined as the design of new chemic..

Before green house effect is studied one needs to know what kind of radiation / sunshine we receive on earth. 'Sunshine' is a common man's term indicating all that we receive from sun. In a shallow perspective of common man, it may simply, mean light. But in a deep scientific me..

Green house is usually a type of glasshouse used for raising tender plants. Air inside the green house is usually warmer than the outside, though it receives less solar radiation due to the carbon dioxide present inside, produced by plants (by respiration). This is called '..

>Relative Contribution of Different Greenhouse Gases to Global Warming What aberration is caused in recent 50 - 80 years is, man has added large quantity of green house gases like CO 2 , Methane. This has resulted in changing the global climate. Human activities such as burning ..

Natural Green House Effect - Before interference by any human activities green house effect by a coverage of gaseous blanket was in close equilibrium with earth's surface in the form of equilibria of carbon, oxygen and hydrogen cycles. Contribution of CO 2 by natural decay of pl..

Change in the composition of air due to several human activities has brought about green house effect. Green house effect has brought about following phenomenal changes. The severity of these changes will aggravate further in the next 10-20 years. By 2040, CO 2 level in a..

Before interference by any human activities green house effect by a coverage of gaseous blanket was in close equilibrium with earth's surface in the form of equilibria of carbon, oxygen and hydrogen cycles. Contribution of CO 2 by natural decay of plants and animals or by respiration by a..
