Composition
78% of the atmosphere.
What is the percentage of nitrogen in the air?
The density of air when there is less mass in a given volume.
What is less dense?
Weather occurs here.
What is the troposphere?
The term used to show the amount of electromagnetic radiation reflected from a surface.
What is albedo?
The layer of gases that surrounds Earth.
What is the atmosphere?
21% of the atmosphere.
What is the percentage of oxygen in the air?
Mass/ Volume
What is density?
The main layers of Earth's atmosphere are classified according to changes in this.
What is temperature?
Most incoming UV radiation is absorbed by this.
What is ozone?
Meteors burn up in this layer of the atmosphere.
What is the mesosphere?
Nearly 1% of the earth's atmosphere
Argon
This is the "standard" air pressure.
What is 1 atm or 101,325 Pa
This is in the lower region of the thermosphere and is where auroras occur.
What is the ionosphere?
The name for heat transfer when columns of warm fluid rise, cool, and sink.
What is convection?
A form of energy from the sun that can travel through space.
What is electromagnetic wave?
The combustion of fossil fuels releases this gas into the atmosphere
What is carbon dioxide
Air pressure and air density do this at high altitude.
What is decrease?
The ozone layer is located here.
What is the stratosphere?
Two things that can happen to energy from the sun at Earth's surface.
What are absorption and reflection?
The visible light with the longest wavelength.
What is red light?
The melting of vast deposits of this currently stored in the ocean depths would release this.
What is methane?
This is the formula for calculating air pressure.
What is p = ρgh
(pressure = density x acceleration due to gravity x height)
This layer has high temperature but low heat.
What is the thermosphere?
The process that traps radiated energy from Earth's surface by gases in the air.
What is greenhouse effect?
The temperature in the troposphere ranges from this at its lowest elevation to this at its highest elevation.
16 degrees C to about -55 or -60 degrees C
