Document Summary

Weather: the conditions and activity temperature, humidity, precipitation, air motion, and pressure of the atmosphere at a particular place and time. Climate: the weather of an area averaged over a long period of time. Difference: climate is concerned with the overall weather patterns of an area. The atmosphere responding to uneven heating of the earth by the sun. Incoming solar radiation radiation from the sun is the driving force that creates all weather on earth (thus creates weather). The layers of the atmosphere filter out some of the most harmful types of electromagnetic radiation. The radiation that gets through is called insolation. Atmosphere of earth: layer of gases surrounding the planet earth that is retained by earth"s gravity. Exosphere molecules from atmosphere escape into space satellites orbit in this layer. Thermosphere hottest layer, high energy rays from sun are absorbed. Contains 19% of the atmosphere"s gases and the ozone layer, which absorbs harmful rays from the sun.
