Document Summary
Weather: short term state of the atmosphere with respect to temperature, moisture, wind velocity and barometric pressure. Greenhouse effect: controls warmth of bodies of water and climate, degree of reflecting infrared radiation back to earth carbon dioxide, methane. Presence of co2 on venus suggests climate was once the same. Energy from impacts: earth is impacted by 100-1000 tonnes of dust every day. Meteoroid impacts cause massive energy releases, even if small. Atmosphere: composed of multiple layers all with their own physical and chemical properties. Air thin and responsive to solar radiation, dramatic temperature changes. The atmosphere is thin today and surface temperatures fluctuate. Here the humid air also is heated, rises, expands, and once it cools condensation begins which releases latent heat. Aid in development and direction of storms. Isobars show how strong/weak wind is the more and closer together the stronger the winds.
