|
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
