ATMOS 1010 Questions with complete
solution 2026/2027
What two gases make up most of Earth's atmosphere? - correct answer ✔Nitrogen and Oxygen
Why does Earth have a more complicated Global Circulation than a simple one-cell model (where air
rises at the equator and sinks at the poles)? - correct answer ✔Earth rotates, has a tilted axis, and has
both land and ocean surfaces.
Which type of energy transfer uses electromagnetic waves? - correct answer ✔Radiation
If we look at an energy balance at the EARTH'S SURFACE, what is the largest contributor to Incoming
Energy? - correct answer ✔Absorbed longwave radiation from gases in atmosphere.
Why do meteorologists convert station pressures to sea level elevation? - correct answer ✔Because
otherwise a surface pressure map would look much like a map of the topography/elevation.
Essentially all important weather phenomena occur in the: - correct answer ✔Troposphere
Louisiana is in what major category of Climate Zone? - correct answer ✔Moist Subtropical Mid-
Latitude Climate
If the outside air temperature is 10 degrees F and the wind speed is 30 mph, what is the wind chill
temperature? - correct answer ✔-12 degrees F
Which layer contains the ozone layer AND why is the ozone layer important? - correct answer
✔Stratosphere and it absorbs harmful UV radiation.
, Which two layers contain 99% of the air in our atmosphere? - correct answer ✔troposphere and
stratosphere
What important thing is deposited when Saharan dust is transported and falls on the oceans and the
Amazon? - correct answer ✔Essential nutrients
What is the primary energy source for weather on our planet? - correct answer ✔The Sun
What is necessary for lightning to form? - correct answer ✔Rising and sinking air
Ice particles
Charge separation
Earth's atmosphere was formed by: - correct answer ✔Volcanic Eruptions
Eventually oxygen built up from prehistoric cyanobacteria called - correct answer ✔stromatolites
Why are greenhouse gases important for life to be able to live on earth? - correct answer ✔They keep
the Earth's temperature warmer than it otherwise would be.
How can fire come out of lake ice in Siberia - correct answer ✔Permafrost has high levels of organic
material (dead plants) that can produce methane
Permafrost is beginning to melt and slumping into lakes.
Bubbles of methane rise up through the lake waters and can be lit on fire.
What is the correct order of the atmospheric layers from bottom to top? - correct answer
✔troposphere, stratosphere, mesosphere, thermosphere
