Atmospheric+Characteristics

The material for this unit can be found in Chapter 17 in your online textbook, and includes the following concepts:
//17.1 (pgs. 476-482)//
 * Difference between weather and climate
 * Composition of the Atmosphere
 * Origin and Formation of atmosphere (see page 495, short paragraph about volcanic outgassing in Earth history)
 * Major components & Variable components & Ozone (ozone layer, ozone formation, ozone hole & depletion, fixing the ozone hole)
 * Primary vs. Secondary pollutants and their sources


 * Properties of the Atmosphere
 * Pressure and Temperature profile with atmosphere (altitude)
 * Layers of the Atmosphere

> ===UNL Seasons Simulator ===
 * Earth-Sun Relationships
 * Motions of Earth: revolution & rotation
 * Earth's orientation & seasons (solstice and equinox dates and significance - what is happening on this day regarding Earth and Sun relationship?)
 * Position of the overhead Sun
 * Length of Daylight



//17.2 (pgs. 483-487)// //17.3 (pgs. 488-495)//
 * Relationship between heat (energy) and temperature (measurement of energy)
 * The three mechanisms of heat transfer and how they occur/affect Earth's atmosphere
 * Conduction, Convection, Radiation (don't worry about the 4 laws governing radiation)
 * EM Energy
 * General characteristics (wavelength, speed, what humans can "see")
 * atmospheric windows (see diagram below regarding this concept)
 * Radiation: Absorption, transmission (radiation goes right through with little change), and reflection
 * Reflection vs. scattering
 * Greenhouse Effect (DOES NOT EQUAL GLOBAL WARMING)
 * Greenhouse gasses
 * Temperature Controls
 * Amount of solar radiation received - main cause is variations in latitude - direct sunlight vs. indirect or shallow angle sunlight
 * Heating of land vs. water
 * Geographic position
 * Windward (from ocean to land) vs. Leeward (from land to ocean)
 * Landforms' influence, for example mountain ranges cutting off locations from marine influenced climate & temperatures
 * Altitude
 * Cloud cover & Albedo
