100
The mass of air surrounding a planet
What is atmosphere
100
In general, should atmospheric pressure increase or decrease as altitude increases?
What is decrease
100
What is the abbreviation for atmosphere?
What is atm
100
What is the layer closest to the earth?
What is the troposphere
100
If the earth's atmosphere contained twice the number of molecules it does today. Would the atmospheric pressure be great than, equal to, or less than it is now?
What is greater than
200
The pressure exerted by the atmosphere on all objects within it
What is atmospheric pressure
200
Is Italian dressing a homogeneous or heterogeneous mixture?
What is Heterogeneous
200
Is air resistance greater or less the higher a plane travels?
What is less
200
As you send a data-gathering balloon into the atmosphere how will you know when the balloon enters the stratosphere?
What is when the temperature starts to increase instead of decrease
200
Two vials contain air samples taken at different altitudes. The first is composed of 21% oxygen, 78% nitrogen, and 1% other. The second is the 95% helium, 4% hydrogen, and 1% other. Which came from the homosphere?
What is the first one.
300
An instrument used to measure atmospheric pressure
What is a barometer
300
If an airplane travels at altitudes of over 4 kilometers, it is required to have a special oxygen supply for the pilot. As you just learned, however, that altitude is well within the homosphere, where the air is 21% oxygen. Why, then, does the pilot need a special oxygen supply at this altitude?
What is there is a lot less air at that altitude.
300
Which atmosphere layer can radio signals actually bounce off of?
What is the ionosphere
300
Which layer has jet streams?
What is the stratosphere
300
A plane is experiencing a LOT of problems because of a storm in the area. Is the plane flying in the troposphere or the stratosphere?
What is the troposphere
400
Narrow bands of high-speed winds that circle the earth blowing from east to west
What is Jet Stream
400
Those who are for the CFC ban claim that skin cancer rates have increased in Australia as a result of the "ozone hole." Although skin cancer rates have increased in Australia (an around the world), why is it hard to believe that the increase is a result of the ozone hole?
What is because the "hole" is centered over Antarctic, and it exists for only a short time and skin cancer rates are increasing around the world, not just by the "hole".
400
What is the average weight in pounds of atmospheric pressure at sea level?
What is 14.7 pounds
400
Which layer protects us from meteors?
What is the mesophere
400
As you are outside on a cold winter night, you begin to shiver from the cold. Your companion says that you are shivering from heat. Is your companion correct? Why or why not?
What is correct. Heat is the energy that is being transferred. Energy is being transferred from your body to the surrounding air.
500
A measure of the energy of random motion in a substance's molecules
What is temperature
500
Those who are against the CFC ban point out that CFCs are 4 to 8 times heavier than the nitrogen and oxygen in the air. As a result, they say, there is no way that CFCs can float up to the ozone layer. Why are they wrong?
What is In the polar vortex, the steady rush of wind pushes them up to the ozone layer with ease.
500
What causes the aurora?
What is the result of high-energy collisions between ionized particles in the ionosphere. The collisions involve a lot of energy, and some of the energy is converted to light.
500
Name the 3 regions of the homosphere, from lowest to highest
What is troposphere, stratosphere, mesosphere
500
Why will the ban of CFCs most likely result in a tragic loss of human life?
What is because refrigeration, surgical sterilization, and firefighting will all be less efficient, causing death by starvation, death by eating food-borne illness, death by surgical infection, and death by fire.
