Monday
Atmosphere
The mass of air surrounding a planet
Greenhouse Effect
The process by which certain gasses (principally water vapor, carbon dioxide, and methane) trap heat that radiates from the Earth.
Pressure
the force (weight) applied over a unit of area
Atmospheric Pressure
Heat
Energy that is transferred as a consequence of temperature differences.
Temperature
Does Temperature measure heat?
No, it measures how much energy is in an object.
Radiation
The transfer of energy by waves
Conduction
The transfer of heat energy by contact
Convection
The transfer of heat energy by contact.
If you want to study weather, which region of the atmosphere would you study?
Troposphere
If you want to study the ozone layer, which region of the atmosphere would you study?
Stratosphere
If you want to study the aurora borealis, which region of the atmosphere would you study?
Ionosphere
Which layers of the atmosphere are in the homosphere?
The troposphere, stratosphere, and mesosphere
Which layers of the atmosphere are in the heterosphere?
Thermosphere and exosphere
In what layers of the homosphere does temperature increase with increasing altitude?
Stratosphere
If a sample of air is predominately oxygen, did it most likely come from the homosphere or the heterosphere?
The heterosphere
What is the air we breathe mostly made up of?
Nitrogen and oxygen
What percent of the air is made up of Nitrogen?
78%
What percent of the air is made up of oxygen?
21%
What percent of the air is not made up of Oxygen or Nitrogen?
less than one percent
We all know that ice melts because of heat. Why is it correct to say that ice also freezes because of heat?
Heat is energy that is being transferred. To freeze water, energy must be transferred from the water to the surroundings.
If you were able to measure the speed of the molecules in the air while you were traveling up through the troposphere, would the speed of the molecules increase, decrease, or stay the same as your altitude increased?
The average speed of the molecules would decrease.
