Some of the gases in our atmosphere such as carbon dioxide‚ trap heat from the sun reflecting of the earth ’s surface‚ keeping the earth warm. This is called natural green house gas effect. However human activities such as burning of fossil fuels are increasing the concentration of these gases in the atmosphere. These accidental gases are enhancing the green house effect which I know as global warming. The major green house gases include carbon dioxide‚ methane‚ nitrogen and water vapour. Air travel

IGSCE Chemistry Notes Oxides Oxides are used to determine whether an element is a metal or a non-metal. Most non-metals are classed as acidic oxides. While most metals are classed as basicoxides. Acidic Oxides * Reacts with water to form acids * Neutralises alkaline solution to form salt + water Basic Oxides * Neutralises acidic solutions to form salt + water Amphoeteric Oxides * These are non-metals which display both acidic and basic properties Alkaline Oxides * Reacts

is basically packaging and this requires energy basically heat which is obtained from coal‚natural gas‚oil etc. Because of combustion process huge amount of carbon monoxide and carbon dioxide is produced which heat the earth surface. By far‚ the most prevalent of the greenhouse gases is carbon dioxide‚ the molecule that is emitted naturally through the respiration of animals and humans. Since the early 20th century‚ Earth’s mean surface temperature has increased by about 0.8 °C (1.4 °F)‚ with

When sunlight reaches Earth’s surface‚ it can either be reflected back into space or absorbed by Earth. Once absorbed‚ the planet releases some of the energy back into the atmosphere as heat. Greenhouse gases (GHGs) like water vapor (H2O)‚ carbon dioxide (CO2)‚ and methane (CH4) absorb energy‚ slowing or preventing the loss of heat to space. In this way‚ GHGs act like a blanket‚ trapping heat and warming the earth thereby making Earth warmer than it would otherwise be. This process is commonly known

ENVIRONMENTAL PROBLEMS BIODIVERSITY LOSS Biodiversity - refers to the number and size of populations in a community; variability of species in an area In general‚ there are three categorical levels of biodiversity: 1. Genetic biodiversity - involves populations‚ individuals‚ chromosomes‚ genes and nucleotides 2. Taxonomic biodiversity - include kingdoms‚ phyla‚ orders‚ families‚ genera‚ species‚ subspecies and populations - for practical reasons‚

Environmental Pollution Simulation Review and Summary Environmental Pollution Simulation Review and Summary In the simulation “Managing Environmental Concerns and Resources‚” the scenario took place in Eastern Europe‚ in a Casadonia city named Keywich. The main concern of Keywich’s City Council is the increasing population of the town and the negative effects it can have on the economy‚ environment‚ culture and society. In the past Keywich was a regular recipient of the Casadonia Greenbough

pollution and in this way help the environment. There are many types of pollution such as: smog‚ acid rain‚ and greenhouse gas emissions. The causes of these pollutants include carbon monoxide‚ hydrocarbon‚ and nitrogen oxide‚ as well as various sulfur compounds. Pollutants are released into the air for several reasons. One reason is that diesel fuel does not burn as cleanly as natural gas. These pollutants are released into the atmosphere by the burning of the fuel. Automobiles are responsible

America’s Foreign Oil Dependency: What are the options to stop this crisis? For Professor Sharon Mitchener From August 11‚ 2006 BUS 531 Research Proposal Abstract The topic of this paper is America’s foreign oil dependency. The purpose of this paper is to suggest how might America completely destroy or at least greatly mitigate its dependency on crude oil to fuel Americans’ cars‚ especially foreign crude oil. Library literature‚ newspaper articles‚ encyclopedias‚ and the Internet

The best friend of earth of man is the tree. When we use the tree respectfully and economically‚ we have one of the greatest resources on the earth. - Frank Lloyd Wright Trees provide a range of benefits to society. These benefits are both tangible and non-tangible. Tangible benefits are marketable resources g g g that we can measure. Intangible benefits are difficult to measure‚ but improve our quality of life. 1 Most trees in cities or communities are planted to p p provide beauty

OZONE LAYER DEPLETION AND GLOBAL WARMING OZONE LAYER DEPLETION AND GLOBAL WARMING. The ozone layer acts as a giant sunshade‚ protecting plants and animals from much of the sun’s harmful ultraviolet radiations. Ozone forms a layer in the stratosphere‚ 15-40 km above the earth surface. If the ozone in the atmosphere from the ground level to a height of 60 km could be assembled at the earth’s surface‚ it would comprise a layer of gas only about 3mm thick. Global stratospheric ozone
