Layers of the Atmospshere
What is the first layer of the atmosphere?
Troposphere
Describe the greenhouse effect.
The greenhouse effect helps keep the earth warm by trapping heat in during the night to keep it from getting too cold and radiating heat out during the day to avoid getting too hot.
Waves
These 2 gases make up 99% of earth's atmosphere.
Nitrogen and Oxygen
Define Radiation
The transfer of energy by waves.
Name all layers on the atmosphere IN ORDER
Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
What are the 2 main greenhouse gases?
Carbon dioxide and water vapor
Heat is transferred by conduction through _______.
Contact
Temperature in earth's atmosphere layers change with _______.
Altitude
Define Conduction
Heat is transferred from molecule to molecule by contact
This layer of the atmosphere can reach very high temperatures because it absorbs the highest amount of energy from the sun.
Thermosphere
What are some human actions that have effected the greenhouse effect?
Deforestation, burning fossil fuels, industrial processes.
What are the 3 steps in the heat transfer cycle?
Radiation, conduction, and convection.
Warm air ______ and cool air ______.
Rises, sinks
Define Convection
The transfer of heat by a current, usually by a liquid or a gas.
This layer of the atmosphere has no upper limit.
Exosphere
human actions that changed the greenhouse effect have caused what phenomenon to occur?
Global warming
________ transfers heat through currents.
Convection
Depending where you are on earth, water vapor can make up to ______% of the atmosphere.
4%
Define Scattering
Occurs when a light wave strikes a particle and bounces off in some other direction.
This is where all of earth's weather occurs
Troposphere
There would be no ____ on earth without the greenhouse effect.
Life
What 2 currents does convection transfer heat through?
Liquid and gas currents.
The ________ is the main reason we are able to sustain life on earth.
Atmosphere
Define Solar Energy
Energy from the sun
