Atmosphere
the relatively thin layer that forms Earth’s outermost layer
air pressure
the pressure caused by the weight of the collum of air pushing down on an area
barometer
an instrument used to measure changes in air pressure
electromagnetic waves
a wave made up of a combination of a changing electric field and a changing magnetic field. 2) a wave that can transfer electric and magnetic energy that can travel through a vacuum of space
altitude
an elevation above sea level
convection
the transfer of thermal energy by the movement of a fluid
conduction
the transfer of thermal energy from one particle of matter to another
radiation
the transfer of energy by electromagnetic waves
scattering
a reflection of light in all directions
greenhouse effect
the trapping of heat near a planet’s surface by certain gases in the planet’s atmosphere
What the atmosphere consist of
nitrogen, oxygen, carbon dioxide, water vapor, and other gases, as well as particles of liquids and solids
Layers in the atmosphere
troposphere, stratosphere, mesosphere, and thermosphere
Troposphere
Lowest Layer of the atmosphere
Troposphere
the densest layer of the atmosphere
Troposphere
Weather conditions vary the most in this layer of the atmosphere
Relationship between altitude and temperature in the troposphere
per 1km increase in altitude there is a 6.5 degree Celsius decrease in temperature
Stratosphere
the layer of the atmosphere that contains the ozone layer
ozone layer
captures heat energy from the sun so the upper part of the stratosphere is where heat has been reflected.
stratosphere
the upper part of this layer is warmer because it is where heat has been reflected from the ozone
mesosphere
the layer of the atmosphere that protects the earth’s surface from meteoroids
meteor
“shooting starts”
thermosphere
the outermost layer of the atmosphere
thermosphere
no definite outer limit
Ionosphere
the lower part of the thermosphere
exosphere
where satellites orbit in the thermosphere
radiation
direct transfer by electromagnetic waves
an example of radiation
the sun
conduction
direct transfer by touching
an example of conduction
heat from the ground
convection
the transfer by movement of a fluid
an example of convection
heat traveling in the air due to density differences
the cause of local winds
pressure differences
the cause of global winds
convention from unequal heating from the earth
