Document Summary

Weather: short term state of the atmosphere with respect to temperature, moisture, wind velocity and barometric pressure. Both weather and climate processes have always had their energy supplied from sun not from inside earth, as for earthquakes and volcanic eruptions. However, many times in this planet"s history process on earth have influenced weather and climate by interfering with sun"s energy. Incoming radiation passes through the atmosphere more readily than outgoing radiation. Presence of co2 on venus suggests climate was once the same, both had roughly similar greenhouses in the early days of climate development. However, the greenhouse of venus strengthened and all the water evaporated, leaving a high surface temperature. On earth, the majority of earth"s carbon was stored in rocks, fossil fuels and plants, with little in the atmosphere something on earth acted as a thermostat but not on venus.
