atmosphere.it is essential for us to know about environment & its pollution. In this presentation we will be able to know about- •Environment •Biosphere •Ecosystem model •Atmosphere •Atmospheric pollution •Primary & secondary pollutants •Acid rain •Ozone depletion •Green house effect •Noise pollution That which surrounds‚ the total sum of the condition of the surroundings within which an organism‚ or group‚ or an object‚exists(including the natural as modified by human activity & the artificial)

The statement says that pollution is a global responsibility‚ but first of all‚ in order to understand the statement and therefore argue the points of view‚ we must state what can be defined as Pollution. The Oxford dictionary states that to pollute an area is to… “…Destroy the purity or sanctity of; make foul or filthy; contaminate or defile…” There are many types of pollution‚ of which the most common is atmospheric pollution. Atmospheric pollution is generally caused by the emissions of substances

I am here to write on behalf of the starving children around the world whose cries go unheard‚ the countless animals dying across this planet because they have nowhere left to go. I am afraid to go out in the sun now because of the holes in the ozone. I am afraid to breathe the air because I don’t know what chemicals are in it. And now we hear about animals and plants going extinct every day- vanishing forever. In my life‚ I have dreamt of seeing the great herds of wild animals‚ jungles and rainforests

Environmental Science Dr Larsen 07/27/10 Air pollution Air pollution has been a problem for years and has caused many infections and depletion of the natural environment. The most recognized depletion is the depletion of the stratospheric ozone layer. Pollution has caused this and has been reason for the increase in human health problems. Indoor air pollution and urban air quality are listed as two of the world’s worst pollution problems in the 2008 Blacksmith Institute World’s Worst Polluted

Air Pollution * Pollutants enter the air from various sources‚ but burning of fossil fuels contributes the most to air pollution. * Exhaust fumes from vehicles contains soot (tiny carbon particles)‚ lead (from cars using unleaded petrol)‚ carbon monoxide‚ oxides of nitrogen and hydrocarbons due to the incomplete combustion of fossil fuels. * Burning of fossil fuels in the combustion engines of vehicles and electrical power stations also releases large amount of carbon dioxide into the

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

detrimental to our health‚ it is important that we protect ourselves. UVC contains the highest amount of energy and a bigger wavelength. When the uv rays enters earth’s ozone‚ UVC does not reach the earth’s surface because of the ozone layer‚ the UVC bonds are broken up due to its oxygen particles breaking down when in contact with the ozone.

in its place making it impossible for anything to grow there. Those trees were a crucial part to the ecosystem and environment‚ which are now changed forever. We also drive cars‚ which emit exhaust‚ which in turn hurts our ozone layer and heats up the Earth. Once the ozone layer is damaged the ice caps melt a little and now the entire environment is changed‚ all thanks to man. Not to mention that biomes are changed as well due to global warming; the ice caps melt a little and the world gets hotter

What causes a volcanic eruption? When a part of the earth’s upper mantle or lower crust melts‚ magma forms. A volcano is essentially an opening or a vent through which this magma and the dissolved gases it contains are discharged. Although there are several factors triggering a volcanic eruption‚ three predominate: the buoyancy of the magma‚ the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber. What follows is a brief description
