absorbed by clouds, gases (like ozone), and particles in the atmosphere. Of the remaining 55% of the solar energy passing through the Earth's atmosphere, 4% is reflected from the surface back to space. On average, about 51% of the Sun's radiation reaches the surface. This energy is then used in a number of processes, including the heating of the ground surface; the melting of ice and snow and the evaporation of water; and plantphotosynthesis. The heating of the ground by sunlight causes the Earth's

to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems. Indoor air pollution and urban air quality are listed as two of the world's worst pollution problems in the 2008 Blacksmith Institute

were going to have a problem with pollution. This caused the US Congress to pass the Clean Air Act and amend it in 1977 and again in 1990. Scientists have found that there are eight main air pollutants, sulfur dioxide, particulates, carbon monoxide, ozone, nitrogen dioxide, lead, carbon dioxide, and hydrocarbons. These air pollutants can cause other problems such as photochemical smog, temperature inversions, and the two most harmful acid deposition and acid rain. Sulfur dioxide is one source of air

run up to $800 and going into the E.R. can cause thousands of dollars.” A problem that these cities face is the ability to pass a law to prevent smokers from smoking in public places. Being in an areas filled with smokers along with pollution, high levels of pollens and being uninsured can cause a high rate of death in children and adults. There are the good and the bad in every situation and the good is that not all cities are filled with pollution and smokers allowing to smoke in public

temperature increase, receding polar ice caps, depleting ozone layers and habitat destruction. These things are all major issues that have become increasingly important because of global warming and there are numbers to prove that this is not just a hoax like some people believe. Increasing levels of Carbon dioxide and other greenhouse gases present in the atmosphere are raising the average temperatures on earth. Receding polar ice caps and rising water levels are destroying habitats for many creatures like

Ozone is a gas found in the upper atmosphere and at ground level of the Earth’s surface. Ozone will mainly be found in two regions of the Earth’s atmosphere closer to our Earth. About 10% of Ozone is found in the region that starts from ground level of the earth known as the troposphere. According to scientific research findings this region of the earth’s atmosphere (troposphere) contains ozone that could be either good or bad depending on how closer it is to the surface of the Earth. The principle

as refrigerants, aerosols, and plant factory emissions affect the status of the ozone layer in the atmosphere? HYPOTHESIS: CFC strongly contributes to the depletion of the ozone layer in the atmosphere. OBJECTIVES: * To measure the amount of CFCs release from refrigerants, aerosols, emissions of factories and other products and materials that contain CFCs. * To determine the degree of CFCs in the ozone layer. * To quantify the percentage between different elements and chemicals
