METR 1102 Final exam ACTUAL
UPDATED QUESTION AND ANSWERS
What is weather - CORRECT ANSWER The condition of Earth's atmosphere at a
particular time and place.
What is climate - CORRECT ANSWER the average weather in an area over a long period
of time
What is earth's atmosphere made of - CORRECT ANSWER Nitrogen (78%) , Oxygen
(21%), Other gases (1%)
What is the difference between constant and variable gases - CORRECT
ANSWER Constant gases are always the same % no matter he circumstance while
variable gases can change %
Dominant gases: Nitrogen & Oxygen (constant)
Water vapor & CO2 (variable)
What have CO2 concentrations done over the last 150 years - CORRECT ANSWER they
have increased because of fossil fuels and deforestation
What is ozone? Where is it found? What does it do that benefits us? - CORRECT
ANSWER good ozone is in the stratosphere and blocks UV radiation and bad ozone is
near the surface and is human made
What is an aerosol? - CORRECT ANSWER A suspension of solid or liquid particles in gas
Ex:dust
vertical structure of the atmosphere - CORRECT ANSWER troposphere, stratosphere,
mesosphere, thermosphere
, lowest two layers in the atmosphere - CORRECT ANSWER Troposphere- temp decreases
w/ height
Stratosphere- temp increases w/ height (ozone)
geostationary satellites - CORRECT ANSWER A satellite that orbits the earth at the same
rate that the earth rotates and thus remains over a fixed place above the equator.
kenetic energy - CORRECT ANSWER energy that a body possesses by virtue of being in
motion. atoms/molecules have KE
potential energy - CORRECT ANSWER Energy that is stored and held in readiness
Warm vs cold air - CORRECT ANSWER warm air expands and cold air compresses
Fahreheit, celsius, and Kelvin - CORRECT ANSWER F, K= C+273, C= (5/9)(F-32)
what are heat capacity and specific heat - CORRECT ANSWER heat energy
absorbed(capacity), heat capacity per unit mass (SH)
What has a higher specific heat, land or water? - CORRECT ANSWER water
latent heating - CORRECT ANSWER Transport of heat from one place to another within
the atmosphere as a consequence of phase changes of water. Heat is supplied for melting,
evaporation, and sublimation of water at the Earth's surface, and heat is released during freezing,
condensation, and deposition within the atmosphere.
Latent heats of evaporation and condensation - CORRECT
ANSWER evaporation(cooling), condensation (cooling)
