Document Summary

Temp has risen . 17*c every decade since the 70s. Temp = average motion of kinetic energy. Heat = transfer of energy from warm objects to cool objects. Sensible heat = the heat we can feel . 129*f was the coldest temp recorded on earth. Measures temp by sensing an electrical resistance. 50% of earth"s surface is covered with clouds at any given time. Moderates temperature cooler days, warmer nights. Consumes more of the energy arriving to earth at oceans surface than over land, simply because there is more water available. 84% of all evaporation on earth is from the oceans: transparency. The transmission of light is different between water and land. Light striking soil does not penetrate the surface, but is absorbed. Light reaching water penetrates surface because of waters transparency. The illuminated zone of the ocean is the photic layer and occurs in some ocean waters up to 300m down.
