 light energy (from the sun) penetrates the atmosphere, gets absorbed by the earth and at the same time converted to heat energy that gets absorbed by the planet’s surface.  Greenhouse gases in the Earth’s atmosphere absorbs infrared radiation.  Insulation

 Tetrahedral Shape  Colorless and Transparent  Greenhouse gases naturally blanket around the earth and keeps the earth warm about 33 degrees Celsius warmer  Traps 20 times more heat than carbon dioxide

 -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.

 -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)

 Communication  Lab  Organization  Deadlines  Technical difficulties  Collaborative Work on Self Reflection
