Atmospheric gases trap and return a major portion of this heat radiating from the earth through this natural and necessary process. Without this process the Earth would freeze over and be uninhabitable. As the number of atmospheric GHGs increases this process is accelerated causing the Earth's surface temperatures to rise.
Anthropogenic Greenhouse Gases
man made activities that rely on processes that put more carbon atoms into the atmosphere rather than those that remove them; ex: cutting down rainforests, combustion
Classification of Greenhouse Gasses
- 3 or more atoms
- the molecular geometry
- ability to bend and stretch with exposure to the infrared radiation ( without breaking apart )
metal bonded with nonmetal
two or more atoms covalently bonded together that have an overall positive or negative charge
natural additional and removal mechanisms
What process adds carbon to the atmosphere?
What process removes carbon from the atmosphere?
atoms of the same element that have the same number of protons but differ in number of neutrons, therefore they have different atomic masses
Average atomic mass
(mass of isotope)(decimal of %) + (mass of isotope)(decimal of %) = Avg. atomic mass
answer should be very similar to atomic weight
