dispersed into space. Greenhouse effect is the problem of gradual rise of gases such as carbon dioxide in the air surrounding the earth which traps the heat if the sun. Greenhouse gases are any of the gases that are thought to cause green house effect. Carbon dioxide is the main green house gas. The gas contributes over 50% of green house effect. The following are some of the sources of carbon dioxide in the environment or the atmosphere. The main human activities that contribute

experiment‚ we measured the mass of 4 gasses; oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest was helium. In fact‚ helium and

named Svante Arrhenius first called attention to the idea the carbon dioxide can raise the earth temperature. 2. Causes (a.) Greenhouse gases build up in the atmosphere which causes earth temperature to rise. C. Topic Sentence- Global warming is an extremely serious problem. 1. Negative effects (a.) If the earth is too hot then it wouldn’t be able to have life on it. 2. How serious (a.) If we don’t stop putting more carbon dioxide in the atmosphere then the earth will get to hot for life on

Global Warming One of the biggest problems facing the world today is global warming. Many scientists believe that our production of carbon dioxide and other greenhouse gases is having a heating effect on the atmosphere‚ and this could be very dangerous for human life. This essay will examine the problem of global warming and suggest some ways of solving the problem. Many problems could result from global warming. One of the biggest problems is rising sea level. This could result in the flooding

heating and powering. Burning Fossil fuels increase carbon dioxide gases which in turn traps the suns heat in the atmosphere. Secondly deforestation adds to the rise in green house gases. Deforestation is the clearing of trees for other gages such as farming‚ homes‚ wood‚ paper and Etc… Trees act like a flitter they clean and rid air of carbon dioxide threw the process know as photosynthesis. Deforestation increases the amount of carbon dioxide in the atmosphere leading to the green house effect

The Enhanced Greenhouse Effect For the past ten thousand years the earth’s climate has been extremely good and beneficial to mankind. Today however ‚ major changes are taking place. Humans beings are changing the face of the entire planet by destroying the rain forests and pumping our pollutants into the air and water. Some of these gases are very toxic and they are destroying our ozone layers which allows life to exist on earth These things are changing the make-up of the earth’s biosphere

global emissions coming from our country. There are many causes of the greenhouse effect. The most prevalent greenhouse gas is Carbon dioxide or CO2. Carbon dioxide and it’s fellow greenhouse gases are released in agricultural practices world wide. They are released by the burning of fossil fuels. There are many invaluable methods in each of these areas to produce Carbon dioxide. In agriculture there are dozens of ways that greenhouse gases are produced world wide. The clearing of land and the subsequent

Gas exchange or respiration in humans is the means by which getting oxygen from air into the blood and carbon dioxide out of the blood into the air. Humans must exchange these gases with the environment because oxygen is essential for cells‚ which use this vital substance to release the energy needed for cellular activities. In addition to supplying oxygen‚ carbon dioxide needs to be removed in order to prevent the buildup of this waste product in the body tissues. As breathing is the act or process
