MET 140 EXAM 1 QUESTIONS AND ANSWERS 100% SOLVED
Gas composition of the atmosphere - ANSWER 78% nitrogen
.09% argon
21% oxygen
.06% other
.035% carbon dioxide
Values of standard atmospheric pressure - ANSWER 1013.25 hPa(hectopascals)
1013.25 mb(millibars)
29.92 inches of mercury
Layers of the atmosphere in order(lowest to highest) - ANSWER troposphere
stratosphere
mesosphere
thermosphere
What layer does temperature decrease with height in - ANSWER Troposphere & Mesosphere
What layer does temperature increase with height in (what layer has an inversion) - ANSWER
Stratosphere & Thermosphere
, What is a temperature inversion - ANSWER When temperature increases with height
What does isothermal mean? - ANSWER Constant temperature
Why is there a temperature inversion in the stratosphere? - ANSWER Because of the ozone
layer (the ozone layer reflects UV rays which makes the top warmer)
What is the difference between temperature and heat? - ANSWER Temperature is the average
movement of molecules in a substance
Heat is the transfer of energy between two objects because of temperature differences
Boiling and Freezing point of water in Fahrenheit - ANSWER Freezing- 32 degrees
Boiling- 212 degrees
Convert Fahrenheit to Celsius - ANSWER 5/9 (F - 32)= C
Boiling and Freezing point of water in Celsius - ANSWER Freezing- 0 degrees
Boiling- 100 degrees
Convert Celsius to Kelvin - ANSWER C + 273.15= K
