Layers
The mass of air surrounding a planet
What is atmosphere?
All molecules, including the invisible gas molecules making up out atmosphere have this and it's always changing.
What is energy?
The pressure the atmosphere exerts on all objects within it.
What is atmospheric pressure?
The most abundant gas in the air
This region in Earth's atmosphere is uniform in its composition and ranges between (0 km - 85 km)
What is the homosphere?
Energy that is transferred as a consequence of temperature differences.
What is heat?
The force (weight) applied over a unit of area
What is pressure?
This gas is important for the body functions of many living things and it helps carry out photosynthesis.
What is carbon dioxide?
This region in the Earth's atmosphere depends highly on the altitude and is found >85 km.
What is the heterosphere?
The transfer of heat energy by waves through air or empty space.
What is radiation?
Scientists measure air pressure with this instrument.
What is a barometer?
The process by which certain gases trap heat that radiates from Earth
What is the greenhouse effect?
This layer of the Earth is found in the heterosphere region of the atmosphere. Much of the UV radiation from the sun is absorbed in this layer.
What us thermosphere?
The transfer of heat energy from molecule to molecule by contact.
What is conduction?
Since we often worry about the atmospheric pressure only in terms of whether it is above or below the average sea-level atmospheric pressure, there is another unit we can use, this unit is called ________.
What is atmosphere (atm)?
Temperature is a measure of the energy of random motion in a substance's molecules. Molecules traveling at this speed have a higher temperature.
What is fast speed?
This layer of the Earth's atmosphere is located in the homosphere region and is composed mostly of oxygen. The temperature stays constant until about 20 km, where the ozone layer is located.
What is the stratosphere?
The transfer of heat energy through a liquid or gas by currents.
If 1 atm is measured during, what is the psi?
Greeenhouse gases tend to absorb the infrared light Earth radiates. These three gases play a big role in the greenhouse effect.
What is carbon dioxide, water vapor, and methane?
