Cloud Types Common cloud classifications Clouds are classified into a system that uses Latin words to describe the appearance of clouds as seen by an observer on the ground. The table below summarizes the four principal components of this classification system (Ahrens‚ 1994). Latin Root | | Translation | | Example | cumulus stratus cirrus nimbus | | heap layer curl of hair rain | | fair weather cumulus altostratus cirrus cumulonimbus | Further classification identifies clouds

Global positioning system (GPS) The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites that orbit the earth at approximately 12‚000 miles above surface and make two complete orbits every 24 hours. Placed into orbit by the U.S. Department of Defense the GPS was originally intended for military applications‚ but in the 1980s‚ the government made the system available for civilian use. GPS works in any weather conditions‚ anywhere in the world

Atmospheric Issues SCI/275 August 25‚ 2013 Professor Ed Mata Atmospheric Issues In today’s society there is much pollution that can cause an individual to become very sick or death can occur from the many atmospheric issues such as ozone depletion in our society. There are many things that contribute to ozone depletion in our atmosphere as well as indoor pollution such as radon which can cause certain cancers and certain deaths. There is also a lot of indoor air pollution which can cause

of the atmosphere surrounded by ozone (15 to 30 Kms) is known as ozonosphere. Ozone layer is a protective stratospheric layer‚ also known as ozone umbrella. Ozone concentration differs by about 10 ppm in stratosphere compared to 0.05 ppm in troposphere. It acts as a protective shield for the man‚ animals and plants by filtering out the lethal ultraviolet rays from reaching the earth’s surface. If the ozone layer is not there‚ the harmful ultraviolet rays will reach to the lower atmosphere and

Abstract. In a world that is becoming increasingly industrialized‚ and in a world where more people can afford to drive cars‚ air pollution is becoming a very big problem. While there are those who would debate whether or not our air pollution is causing global warming‚ versus the earth ’s natural warming process since the last Ice Age. Definitive proof may or may not be found anytime soon. What is certain‚ however‚ is that there are confirmed problems caused by air pollution. These problems include

in chemical and biological research‚ in a technique called carbon labelling. Carbon-14 atoms can be used to replace nonradioactive carbon‚ in order to trace chemical and biochemical reactions. - It is produced in the upper layers of the troposphere and the stratosphere‚ by thermal neutrons absorbed by nitrogen atoms. - Plants fix atmospheric carbon during photosynthesis‚ so the level of carbon in plants and animals when they die approximately equals the level of carbon in the atmosphere

The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger‚ additional ultraviolet rays are allowed to pass through. These rays cause cancer‚ cataracts‚ and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970‚ Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started
