Document Summary
Be able to describe/explain how atmospheric pressure and temperature change with increasing altitude in the troposphere. With incr altitude-> air pressure decr (compressibility of air) Bc there is less air at that altitude: be able to describe/explain/draw diagrams to explain why the poles are colder than the equator and why we experience seasons. Poles are colder b/c earth is spherical. Radiation is spread over a larger area. Radiation has to travel thru greater thickness of atmosphere. Earth"s tilt is the main cause of the seasons. Tilt affects the amount of solar energy reaching diff locations on earth thru year by influencing. Which position would the earth be when the north pole experiences 24 hr nights. Winter solstice: be able to draw out the 3-cell conceptual model and explain how it affects ocean salinity and surface winds.
