METR 1102 UNCC Exam 1 Questions And
Answers 100% Pass
What is weather? - ANS The conditions of the atmosphere right now
What is climate? - ANS The average weather conditions in an area over a long period of time
What was earths early atmosphere made of? Today? - ANS Early - Mostly hydrogen and
helium
Today - Nitrogen, oxygen, argon
Know the difference between constant and variable gases and the dominant ones -
ANS Constant - Nitrogen, Oxygen, Argon, Neon
Variable - Water vapor, carbon dioxide, methane
Which variable gas is the most important for weather and why? - ANS Water vapor, it affects
everything
What have CO2 concentrations done over the past 150 years - ANS Increased by 60-70%
What is ozone and where is it found? What does good ozone do for us? - ANS 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 - ANS Particles (dust, pollen, ect.)
Understand the key properties of the vertical structure of the atmosphere: Density pressure,
temp - ANS 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 - ANS 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 - ANS 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 -
ANS Kinetic = energy of motion (air temp)
Potential
Know the difference between warm and cold air - ANS 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? - ANS Fahrenheit =
U.S
Celsius = Everyone Else
