The lower pie represents the trace gases which together compose 0.038% of the atmosphere. The numbers are from a variety of years (mainly 1987‚ with CO2 and methane from 2009) and do not represent any single source. The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation‚ warming the surface through heat retention (greenhouse effect)‚ and reducing temperature extremes

the pollution. Many people know about air pollution‚ but not everyone knows how hazardous it really is. According to the Environmental Protection Agency the six most abundant pollutants in the air are ozone‚ particulate matter‚ carbon monoxide‚ nitrogen dioxides‚ sulfur dioxides‚ and lead. Ozone is the main component of smog (What). Smog is “a thick haze caused by the action of sunlight on air polluted especially by smoke and automobile exhaust fumes” (Smog). Particulate matter is made up of a mixture

Pollution and Society *By Osanyinpeju* Aisha We all know that pollution in our world effects two essential aspects of our planet: air and water. Although their pollutants are emitted in completely different ways‚ they both harm living organisms. Air pollution is predominately emitted though the exhaust of motor vehicles and the combustion of fossil fuels‚ whereas water pollution is the result of industrial waste and environmental accidents. Our society knows that pollution is harmful and a serious

atmosphere. If the ozone layer were to be gone‚ of course the planet would heat up. It is really our only protection‚ in my opinion‚ from the dangerous rays from the sun. Granted our planet is the third farthest planet from the sun‚ we still need protection. The chemicals we use‚ the exhaust fumes from vehicles and factories‚ and many other things affect this layer of protection. I have found some examples of what could possibly happen if we were to deplete our ozone any more than it already

Effect of Industrial Expansion on the ecosysytem. Pollutants given off by various industries and factories are often considered to be one of the prime factors contributing to air‚ water and soil pollution. According to the Environmental Protection Agency (EPA)‚ it has been estimated that industrial pollution is responsible for almost 50 percent of the pollution present in the United States. There are various wide-ranging effects‚ as well as serious consequences‚ of industrial pollution on the ecological

Air pollution is a major problem facing our environment today. This dilemma is harmful to every living creature on this planet. How can we limit the causes of air pollution? There are industrial as well as residential causes of air pollution. We need to limit the effects of air pollution. We all know it affects the environment‚ but it also can affect us directly. Air pollution needs to be controlled. Air pollution can be defined as pollution in the air. It is all around us. It might not be as clearly

Identify the relationship between the conditions on early Earth and the origin of organic molecules. - Conditions of early Earth: Massive oceans existed Only small landmasses above the surface of the water No ozone layer Large amounts of radiation reached the Earth No free oxygen in the air Large amounts of volcanic activity; heat‚ ash‚ dust and gases into atmosphere Violent electric storms common Atmosphere contained some water vapour (H2O)‚ hydrogen (H2)

Pollution is the introduction of contaminants into the environment. It is cause mostly by human actions‚ but can also be a result of natural disasters. Pollution has harmful effect on living and non-living things in an environment‚ making it difficult to maintain life. There are different types of pollution. The main ones are: 1. Air pollution 2. Water pollution 3. Land pollution 4. Noise pollution Air pollution Air pollution is the accumulation of pollutants into the atmosphere that have
