METR 1102 UNCC Exam 1 ACTUAL
QUESTION AND ANSWERS
What is weather? - CORRECT ANSWERS The conditions of the atmosphere right now
What is climate? - CORRECT ANSWERS The average weather conditions in an area over
a long period of time
What was earths early atmosphere made of? Today? - CORRECT ANSWERS Early -
Mostly hydrogen and helium
Today - Nitrogen, oxygen, argon
Know the difference between constant and variable gases and the dominant ones - CORRECT
ANSWERS Constant - Nitrogen, Oxygen, Argon, Neon
Variable - Water vapor, carbon dioxide, methane
Which variable gas is the most important for weather and why? - CORRECT
ANSWERS Water vapor, it affects everything
What have CO2 concentrations done over the past 150 years - CORRECT
ANSWERS Increased by 60-70%
What is ozone and where is it found? What does good ozone do for us? - CORRECT
ANSWERS Ozone is mostly found in the stratosphere, and is protects us form ultraviolet
rations
Ground level ozone is bad = pollution
What is an aerosol and know some examples - CORRECT ANSWERS Particles (dust,
pollen, ect.)
, Understand the key properties of the vertical structure of the atmosphere: Density pressure, temp
- CORRECT ANSWERS The mass of atoms and the space between them
Molecular density of air: number of molecules in a given volume
Know the two lowest thermal layers in the atmosphere (Troposphere and Stratosphere) - what
does temperature do with height - CORRECT ANSWERS Temp decreases with height in
the troposphere
Temp increase in the stratosphere with ozone
What is geostationary satellite? Know the difference between: visible, IR and water vapor
satellite - CORRECT ANSWERS Geostationary = moves at the same speed of the earth
Visible = Cant use at night because of sunlight needed
IR = shows cloud temperature
Water vapor = shows amount of water vapor
What is potential vs Kinetic energy - how is kinetic energy defined in the atmosphere -
CORRECT ANSWERS Kinetic = energy of motion (air temp)
Potential
Know the difference between warm and cold air - CORRECT ANSWERS How fast the air
molecules are moving.
Warm air is less dense
Cold is heavier
What are the main differences between Fahrenheit, Celsius, and Kelvin? - CORRECT
ANSWERS Fahrenheit = U.S
Celsius = Everyone Else
Kelvin = Scientist, does not go below 0
