Document Summary
Weather and geology: weather due to movement of energy and mass in atmosphere a. i. Heat and water: drives mass-wasting, soils, flood erosion, weather patterns are part of climate c. i. If patterns are changing then climate is changing. Water and weather: water has a high heat capacity, absorbs heat when going from soil to liquid to gas, releases heat when going from gas to liquid to solid, condensing water in clouds provides energy to atmosphere d. i. Water and weather: warmer air can hold more vapor, as air cools, water vapor will condense to droplets at the dew point b. i. Changes with humidity (amount of water vapor: leads to cloud and fog formation c. i. Jet streams: narrow air currents, exist between troposphere and stratosphere, form along boundaries of global cells, may form meanders or waves, steer fronts and storms. Air masses: regions of similar temperature and humidity (amount of water vapor, boundaries between air masses are fronts.
