atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation. A. Nitrogen - 78% - Dilutes oxygen and prevents rapid burning at the earth’s surface. Living things need it to make proteins. Nitrogen cannot be used directly from the air. The Nitrogen Cycle is nature’s way of supplying the needed nitrogen for living things. B. Oxygen - 21% - Used by all living things. Essential

The Concentration of CO2 in the Atmosphere Introduction Carbon dioxide (CO2) is a colorless‚ odorless‚ non-flammable gas that can be produced by cellular respiration and burning of fossil fuels. Many types of industries such as breweries‚ mining ore and the manufacturing of carbonated drinks‚ drugs‚ disinfectants‚ pottery‚ and baking powder; utilize the CO2 gas (Appendix C). Recently Scientist proposed a theory in which CO2 concentration levels above 450ppm will lead to dramatic and potentially

A. Identification of Pollutant in the Atmosphere Carbon Dioxide Carbon Dioxide is a colorless gas having a faint‚ sharp odor and a sour taste; it is a minor component of Earth’s atmosphere formed in combustion of carbon-containing materials‚ in fermentation‚ and in respiration of animals and employed by plants in the photosynthesis of carbohydrates. Though living things emit carbon dioxide when they breathe‚ carbon dioxide is widely considered to be a pollutant when associated with cars‚ planes

The purpose of this essay is to consider the current environmental issues of an enhanced greenhouse effect and global warming with particular reference to the changes that are taking place in response to Greenhouse Gases interacting with the atmosphere and the effects these changes are having on naturally occurring reactions and processes that impact on our planet and our way of life. The aim of the essay is to examine the evidence available to support and refute current claims of imminent threats

sea levels rise‚ which would make them more power for dangerous hurricanes. Hurricanes draw power from warm water. Hurricane Katrina in New Orleans was a great example of the power of the ocean. There are so many things that affect the atmosphere. If the ozone layer were to be gone‚ of course the planet would heat up. It is really our only protection‚ in my opinion‚ from the dangerous rays from the sun. Granted our planet is the third farthest planet from the sun‚ we still need protection

In order to better understand our universe we must first understand our planet and planetary system of which we reside. By understanding Earth’s properties we can get a better grasp of the rest of our solar system. Earth is the best studied of all the terrestrial planets and also where

Scattering in the Earth’s Atmosphere Tony Yuk Hei Chan Abstract Introduction When the sun radiates light to the earth‚ incoming solar radiation often is scattered from its original direction of propagation as it enter earth’s atmosphere. This is due to the scattering effect from different particles in the earth’s atmosphere. When the scattering occur‚ the phase and the polarization of solar radiation are often changed. In this experiment‚ we aimed to investigate the effect of two of the
