-decomposition
-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
-methane
-water vapor - what process gives off carbon dioxide?
- cellular respiration
- source
- something that releases carbon dioxide into the atmosphere
- sink
- 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?
- plants
- 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
- photosynthesis
-
co2+h20-->(in presence of sunlight and chlorophyll) produce c6h1206+o2
*makes glucose which contains energy; releases oxygen - cellular respiration
-
C6H1206+02-->CO2+H20+ENERGY
*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
