CO2 was trapped in the Earth because of the unusual thickening of the Earth’s ozone layer‚ and now it “breathes out” little CO2 than before. The greenhouse effect is bad to the living organisms on Earth because it contributes to a lot of damage to the planet. The human activity that caused the greatest release of greenhouse gases is the smoke released from factories. It releases harmful substances that damage our ozone layer. But‚ there are also other causes‚ such as what Mr. Al Gore said: "Each one

able to see. One step above visible light is ultraviolet radiation. There are 3 major types of ultraviolet radiation: UVA‚ UVB and UVC. The atmosphere usually absorbs UVC before it reaches the Earth. The ozone layer serves as a natural shield to many of the sun’s rays‚ however‚ now that the ozone layer is slowly depleting‚ more and more UV radiation can get through. UVB partially reaches the Earth‚ and UVA completely reaches the Earth. What does UV Index mean? The ultraviolet index or UV Index is an

The planet Earth is emphasized as “the rare Earth” in numerous literatures because of its unique physical conditions and the complicated interactions among all biotic and abiotic systems. Isotope dating indicates the earth was formed approximately from 4.53 to 4.568 Ga‚ according to isotope

trucks‚ and jet airplanes produce the most common pollutants‚ nitrogen oxides‚ gaseous hydrocarbons‚ and carbon monoxide‚ as well as particles of matter like lead. When nitrogen oxides combine with hydrocarbons they form other types of pollutants‚ like ozone‚ peroxyacetylnitrate which stings the eyes‚ and nitrogen dioxide which forms when nitrogen oxides react with oxygen. In cities where transportation is the major cause of pollution‚ nitrogen dioxide colors the sky brown‚ because the nitrogen dioxide

This has made life easy and comfortablefor the user. A country said to be a developed country when it has many technicaladvancements. A small country like japan has succeeded to acquire this prestige becauseof its advancements and applications of technology at a high level. This century is the ageof Science. We cannot

Fossil fuels such as gasoline‚ methane and propane contain mostly carbon. When these fuels are burned‚ they react with oxygen and produce carbon dioxide. Because of our heavy use of fossil fuels‚ the amount of carbon dioxide in the atmosphere has been increasing since the industrial revolution. The destruction of forests which use carbon dioxide also contributes to the increase in carbon dioxide. Most of the light energy from the sun is emitted in wavelengths shorter than 4‚000 nanometers (.000004

Automobile Air Pollution Efforts to improve the standard of living for humans‚ through the control of nature and the development of new products have also resulted in the pollution of the environment. Much of the world’s air‚ water‚ and land is now partially poisoned by pollution. Some places have become uninhabitable. This pollution exposes people all around the globe to new risks from disease. Many species of plants and animals have become endangered or are now extinct. The air pollution comes

ATMOSPHERE – OCEAN INTERACTIONS :: LECTURE NOTES 1. Introduction to the Atmosphere and Ocean J. S. Wright jswright@tsinghua.edu.cn 1.1 O VERVIEW This chapter outlines the main features of the atmosphere–ocean system and motivates the deeper examination to follow. The character of coupled atmosphere–ocean interactions is briefly introduced. Simple energy balance models are derived and used to illustrate the fundamental mechanisms behind variations of temperature with altitude
