methane sources
-natural gas
-rice paddies
carbon dioxide sources
-volcanic errputions
global warming
warming trend in atmosphere that increases daily temperatures because of the green house gases and green house effect
green house gases
GHG are carbon dioxide, methane, and water vapor that are in the air and these 3 gases help to cause the green house effect
green house effect
the sun's rays in the atmosphere bounce off of the earth's surface and this heat gets trapped in the troposphere which heats the atmosphere, leading to global warming
gases in our atmosphere
78% nitrogen
21% oxygen
0.9% argon
remaing percentage of gases are CO2, methane, water vapor, and other gases
earth's average temperature because of carbon dioxide
15 degrees celcius
temperature without green house gases
-18 degrees celcius
3 most naturally produced greenhouse gases
-carbon dioxide
-water vapor
what process gives off carbon dioxide?
cellular respiration
something that releases carbon dioxide into the atmosphere
something that holds carbon dioxide from air or water
Are there more sources than sinks or sinks than sources?
more sources than sinks
what are the most importantcarbon dioxide sinks?
percentages of carbon dioxide sources
65% fossil fuel
33% deforestation
2% by-products of cement production
bromothymol blue (BTB) indicates presence of what?
acid formed by carbon dioxide which is called carbonic acid
co2+h20-->(in presence of sunlight and chlorophyll) produce c6h1206+o2

*makes glucose which contains energy; releases oxygen
cellular respiration

*releases energy, carbon dioxide, and where; the process of photosynthesis starts all over again
Relationship between photosynthesis and cellular respiration
they are inverse processes; photosynthesis makes glucose where as cellular respiration releases the energy from glucose molecules
