Explain acid rain,global warming and green house effect |
| Answer» \tGreenhouse effect is the process by which radiations from the sun are absorbed by the greenhouse gases and not reflected back into space. This insulates the surface of the earth and prevents it from freezing.\tAcid Rain as the name suggests can be said to be the precipitation of acid in the form of rain in the simplest manner. When atmospheric pollutants like oxides of nitrogen and sulphur react with rainwater and come down with the rain, then this results in Acid Rain.\tGlobal warming is a gradual increase in the earth\'s temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. | |
