Document Summary
Most of the processes we consider in unit 3 are those that arise from energy received from sun. The latter part of the unit will consider the collisions between earth and asteroids, meteoroids and comets. Two definitions are needed to get this first section started: Weather: the short-term state of the atmosphere at a given time and place, with respect to variables such as temperature, moisture, wind velocity, and barometric pressure. Of particular interest to us in this course are those short-term weather processes involving storms like hurricanes. Because a very large number of studies are underway to see if these storms will increase in frequency and/or intensity as the current global warming proceeds. Climate: the average long-term weather conditions for a region of earth, including things like average temperature and precipitation. While climate is traditionally dictated by latitude, tilt of earth"s axis or proximity to large bodies of water, the only constant about climate is that it changes!
