GLOBAL WARMING What Is Global Warming? Global warming is the warming of the earth through carbon dioxide (CO2) being pumped into the atmosphere from tailpipes and smokestacks. Then the gases trap heat like the glass in a greenhouse. This is where the term the “greenhouse effect” came from. What’s Happening Scientists say that the barrier insulating the continental ice caps is melting. “The impacts of warming temperatures in Antarctica

combining different forms of filtration can provide near-perfect water. One note to take is that most of the time the more that is filtered‚ the pricier the method is. Three very effective methods of water filtration are “Ion Exchange”‚ UV light‚ and “Ozone”. The most expensive but very effective method of filtering water is through Ion Exchange. It involves replacing ions like Ca2+ and Mg2+ (harmful) with good ions like Na+ or K+. Ca2+ can cause cell injuries and trigger a number of membrane-disruptive

The accumulation of tropospheric ozone at night depends mainly upon the atmospheric concentrations of (B) volatile organics 1. What are they? The six criteria air pollutants are sulfur dioxide‚ nitrogen oxides‚ carbon oxides‚lead‚particulate matter and tropospheric ozone. These six pollutants significantly threaten human health

pollutant known as nitrogen oxide. North American urban areas have ten to a hundred times higher nitrogen dioxide concentrations that nonurban areas. Nitrogen dioxide combined with other gases can for harmful substances. It can produce nitric acid‚ ozone pollution‚ and photochemical smog. Another pollutant from the automobile is photochemical smog. This pollutant results from the interaction of sunlight and combustion products in automobile exhaust. Sulfur dioxide is another harmful chemical‚ which

There are several factors that cause air pollution. The first factor is Ozone. As a report‚ Ozone forms as a product of solar energy and photochemical reactions of pollutants. It is easy that the highest concentrations of ozone in the atmosphere occur when sunlight is the highest temperature (Kleinman‚ 2000). In our daily life‚ vehicle exhaust‚ industrial emissions‚ gasoline vapours are some of the most important sources of ozone (Air pollution‚ 2010). The second factor is Airborne Particles. It is

human health; however‚ the rise in population on the planet causes an interaction between nature and humans which in the end results in environmental issues increasing on a global scale. Population is determined by the relationship of two factors. One being birth rate and the other is death rate. If the number of deaths is less than the number of births then the population is growing larger. In John Laffin’s novel The Hunger to Come data is present showing that the population will continue

And due to ozone depletion in the recent decades‚ more UVB radiation reaches the surface of the Earth and hence able to penetrate through sea at a greater depth‚ causing detrimental damages to marine life(1‚8). UVB radiation forms 1.5% of the solar irradiance energy(6). It is undetectable by human eyes and is found

algae and other plants. Statistically speaking‚ it is composed of 79% nitrogen‚ 20% oxygen and 0.036% carbon dioxide. The rest is made up of small amounts of other gases. The atmosphere is divided into four layers. The atmosphere also has a layer of ozone. The layers of the atmosphere listed from lowest altitude to highest altitude are the troposphere‚ stratosphere‚ mesosphere and thermosphere. The troposphere extends from the Earths surface up to about 14 kilometers in altitude. All human activities

Oxygen is one of the most important and abundant elements on Earth. About 46 percent of the Earth’s crust is oxygen. It is colorless and odorless and makes up about 20.95 percent of the atmosphere by volume. Oxygen exists in water as part of water molecule‚ in the atmosphere as a gas‚ in the Earth’s crust and in an enormous variety of rocks and minerals. It can also be released from the plants through photosynthesis. Moreover it is very essential for life and is part of almost every biological molecule
