Transcript of Explaining The Greenhouse Effect - Science 9G

The greenhouse effect is caused by the emission of various greenhouse gases. The three main gases are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20). All three of these greenhouse gases are produced by the activities of man in some way. Nitrous oxide is primarily emitted by agricultural activities and sewage treatment. Carbon dioxide is released primarily by the burning of fossil fuels, and the production of carbon dioxide is usually related to energy production activities. Agricultural activities, waste management, and fossil fuel burning are the main contributors of methane (yes, cow farts do have a significant role). While there are natural contributors to the greenhouse effect, man is the most significant contributor. In fact, these increases have been seen almost exclusively after the industrial revolution. Causes Of The Greenhouse Effect By Cameron Luck 9G - Explaining The Green House Effect Long Term Effects Of The Greenhouse Effect Rising temperatures would raise sea levels as well, reducing supplies of fresh water as flooding occurs along coastlines worldwide and salt water reaches inland.
Many of the world’s endangered species would become extinct as rising temperatures changed their habitat.
Millions of people also would be affected, especially poor people who live in precarious locations or depend on the land for a subsistence living.
Certain vector-borne diseases carried by animals or insects, such as malaria, would become more widespread as warmer conditions expanded their range. Word Equations For Processes That Release Or Store Carbon Dioxide glucose + oxygen --> carbon dioxide + water

hydrocarbon + oxygen --> carbon dioxide + water The Greenhouse Effect Using The Big Idea Of Energy Transfer Generally, the atmosphere contain mainly of nitrogen and oxygen with trace amounts of water vapor. Now, due to excessive emission of carbon dioxide and nitrogen oxides from fossil fuels, methane from organic waste materials and other gases begin to be part of the atmosphere. The Heat capacity of the atmosphere increases as the amount of the emission increases. The Ultraviolet rays from the sun normally bounces back to the space but now it is absorbed by these gases through radiation ( a mode of heat transfer). As the heat is absorbed, the more turbulent the atmosphere becomes. Explaining The Greenhouse Effect In Terms Of My Model Of A Greenhouse In terms Of My Model Rays from the sun pass through the glass in the greenhouse the plants absorb the rays, but when the plants release this heat some heat is reflected back as all the heat doesn't pass back through therefore heating the greenhouse and providing a temperature for the plants to grow in Comparing It With The Earth's Atmosphere The Earth shows the same principle of heat passing through the atmosphere, being absorbed by the surface and releasing the heat but some of it getting trapped in the atmosphere by all the gasses in the air. However in a greenhouse the atmosphere would be the glass and the surface being the plants Evaluating A Model Of The Greenhouse Effect This is a very good and detailed model of the greenhouse effect as not only does it show how the process works it also gives us an explanation for the arrows and also it shows the speed of each arrow. however the only thing this model doesn't take into account is the weather conditions.
