Premium Air pollution Global warming Ozone
Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth’s stratosphere (the ozone layer)‚ and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena‚ there are also springtime polar tropospheric ozone depletion events. The details of polar ozone

Chemistry at Work: CO2 and the Greenhouse Effect Greenhouse gases and global warming have received increasing attention in recent years. The identification of the ozone hole in 1985 combined with unusual fluctuations in global temperatures have combined to capture the eye of the global media. Recent scientific study and analysis of the greenhouse gases has added to this interest. Greenhouse gases in the atmosphere have an important influence on the climate of our planet. Quite simply‚ greenhouse

Air Pollution What is Air Pollution? * Air pollution can be defined as the presence of any harmful material in the air and the atmosphere that can cause damage to human beings and other living organisms. * Air pollution could also be in the form of disturbances to the normal composition of the air such that there is an undesired effect on the environment or living things. * Under normal circumstances‚ the earth’s atmosphere consists of nitrogen (~78%)‚ oxygen (~21%)‚ small amounts

Chlorofluorocarbons Chlorofluorocarbons are non-toxic‚ non-flammable chemicals that are mainly used in the manufacturing of aerosols‚ blowing agents for foams and packing materials‚ as solvents‚ and as refrigerants. They are classified as Halocarbons‚ a class of compounds that contain carbon and halogen atoms‚ and are amongst a group of substances called "greenhouse gases". They eat away at our ozone and raise the temperature of our planet significantly‚ causing detrimental damage to our planet

atmosphere is made up of nitrogen 78%‚oxygen 21%‚argon 0.9%‚carbon dioxideo0.03% and small amount of trace gases ‚helium ‚neon‚ krypton‚ xenon‚ hydrogen and ozone. In addition‚ there is some amount of water vapour. The atmosphere exists in layer called troposphere‚stratosphere‚ionoshhere and exosphere in that order from the surface of earth. The atmosphere is not static and is moving constantly with respect to earth surface‚both horizontally and vertically. CAUSES OF AIR POLLUTION More than two centuries

GENERAL SCIENCE POINTERS BASIC CONCEPTS AND LAWS Science and Technology Science - is a systematic study that is concerned with facts and principles‚ and methods that could be observed in our natural or physical and social environment. It comes from the Latin word ’scire’ that means ’to know’. - is both a body of knowledge and a process – away of thinking‚ a way of solving problems The Branches of Science THE PHYSICAL SCIENCES • Physics: The study of matter and energy
