Document Summary
Weather: the short-term state of the atmosphere at a given time and place, with respect to variables such as temperatures, moisture, wind velocity, and barometric pressure. Climate: the average long-term weather conditions from a region of earth, including things like average temperature and precipitation. Both weather and climate processes have their energy supplied from the sun. Today, the primary climate-changing influences is from human-related processes. Processes on earth can influence weather and climate by interfering with the suns energy. Greenhouse strength controls the warmth of bodies of water and for atmosphere. Venus is often called the twin" of earth b/c of the size similarity: receives 2x the solar radiation that earth gets, early days both had similar greenhouse gasses made of co2 emissions coming from volcanoes. & both had oceans of water: greenhouse of venus strengthened to the point that all the water evaporated {surface. Meteoroids, asteroids, and comet impacts are also external energy sources.
