  1. Emissions of Methane SankaWijesinghe, Yuki Choi, Natsumi Oka

  2. Chemistry Aspect

  3. Physics Aspect • -Earth's average temperature is 16 degrees<--> 34 degrees higher than the Moon's average temperature. • -Atmosphere composition: 71% nitrogen, 21% oxygen, 1% greenhouse gases. • -Greenhouse gases include: water vapor, nitrous oxide, methane, and carbon dioxide.

  4. Physics Aspect (continued) • -Each gas has its own natural frequency (resonance)-->Wave lengths match the frequency. • -The majority of the radiations are penetrated to the Earth. • -Resonance + Dipole moment = Re-radiation (*Dipole moment= the measure of polarity in a covalent bond)
