How to submit: Upload answer file (.doc, .pdf or .jpg file with answers via Blackboard); also, submit hard copies in

class on the due date

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 0 Celsius and the

0 Farenheight scales coincide? Show your work
