SECTION I: NAME THE PHENOMENON / EFFECT / MECHANISM (5 points)

 The occurrence of higher temperature in urban areas as compared to surrounding rural areas: _____________  The absorption of longwave terrestrial radiation by atmospheric gases such as carbon dioxide and methane:

_______________  Mechanism /method of heat transfer involved when you touch a hot surface: _____________  The name of the isotherm that connects all points of highest mean temperature: ____________  The zone of convergence of the trade winds: _________________________

SECTION II: TRUE OR FALSE (10 points)

 Tropospheric ozone protects us from the harmful UV rays of the sun: ___________  The lower atmosphere gets heated mostly from terrestrial radiation and to a lesser extent from insolation:

_________  At the Equator, low angle of insolation, variable day lengths, and high seasonal variations create an energy

deficit: ______________  In the Northern Hemisphere, the coldest time of the year occurs in December at the time of the winter solstice:

____________  Nitrogen and oxygen are the most abundant greenhouse gases in the atmosphere: __________  You would expect a tropical island to have a high degree of continentality: _________  Evaporation is a cooling mechanism: ______________  Weather (rain, fog, storms etc) occur primarily in the troposphere: _______________  Emission of CFCs cause stratospheric ozone depletion: _________________  Closer the isobar  steeper the pressure gradient  weaker the wind: ____________

SECTION III: CIRCLE THE CORRECT ANSWER CHOICE (5 points)

 Reykjavik, due to its __________ (coastal/inland) location, enjoys a _____________ (continental/maritime) climate.

 Land has a __________ (higher / lower) specific heat than water and therefore heats more __________ (slowly / quickly). This is one of the main reasons why temperature in the interior of large landmasses is more ________ (extreme / moderate) than temperature in coastal areas.

SECTION III: TEMPERATURE MEASUREMENTS (5 points)

1) If the temperature at the surface of Earth (at sea level) is 40°C, what is the temperature at 2000 meters if the normal lapse rate is 6.4 C°/1000 m? Show your work

2) What is the temperature at which the 0Celsius and the 0Farenheight scales coincide? Show your work
