 What is the greenhouse effect? | light passes through the atmosphere; hits the earth; the light is absorbed and changed; the heat dissipates back to outer space; some heat is trapped by greenhouse gases and warms the earth |
| Explain why the green house effect is important | The green house effect keeps the Earth warm; without it earth would be an ice plant |
| 1st greenhouse gas and source: | CARBON DIOXIDE-a by product of combustion (burning) the burning of fossil fuels has drastically increased the amounts of carbon dioxide |
| 2nd greenhouse gas and source: | METHANE-produce by anerobic digestion (without oxygen) produced in the wetland nice paddy, stomache tracts of cows and other organisms like termites |
| 3rd greenhouse gas and source: | CHLOROFLORO CARBONS-a group of man made chemicals developed in the 1950's and used in many products. |
| what is global warming? | rise in global temperature DUE to an increase in greenhouse gases; too much is being absorbed |
| If global warming is occuring, what are some predicted outcomes? | climate changes; ice caps meltings; sea levels rising and flooding coastal areas |
| How the amount of greenhouse gases can be reduced | Carbon dioxide level can be reduced by less combustion especially fossil fuels; This can be done by energy conservation and the developement of alternative sources; Less deforestation will also reduce the amount or carbon dioxide; Methane can be reduced with new technologies that will collect methane released and use as an energy source; Many sewage treatment plants are already doing this; CFC's have been banned in the U.S. and many other countries levels are banned being decreased |
| What is the most abundant greenhouse gas? | Carbon dioxide |
| Why would curbing greenhouse gases be difficult | Fossil fuel addicted; entire economy is based on fossil fuels |
| What is the relationship of the oceans to the greenhouse effect? | Oceans store CO2; much more in ocean then atmosphere, cold water can hold more CO2; If the atmosphere warms ocean warm |
| What is the relationship between deforestation and the greenhouse effect? | Trees remove CO2 from the atmosphere less trees more CO2 in atmosphere; Tree tops are left- termites invade "slash" = methane= greenhouse Gas |
