the relatively thin layer that forms Earth’s outermost layer

the pressure caused by the weight of the collum of air pushing down on an area

an instrument used to measure changes in air pressure

1. 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

an elevation above sea level

the transfer of thermal energy by the movement of a fluid

the transfer of thermal energy from one particle of matter to another

the transfer of energy by electromagnetic waves

a reflection of light in all directions

the trapping of heat near a planet’s surface by certain gases in the planet’s atmosphere

nitrogen, oxygen, carbon dioxide, water vapor, and other gases, as well as particles of liquids and solids

troposphere, stratosphere, mesosphere, and thermosphere

Lowest Layer of the atmosphere

the densest layer of the atmosphere

Weather conditions vary the most in this layer of the atmosphere

per 1km increase in altitude there is a 6.5 degree Celsius decrease in temperature

the layer of the atmosphere that contains the ozone layer

captures heat energy from the sun so the upper part of the stratosphere is where heat has been reflected.

the upper part of this layer is warmer because it is where heat has been reflected from the ozone

the layer of the atmosphere that protects the earth’s surface from meteoroids

“shooting starts”

the outermost layer of the atmosphere

no definite outer limit

the lower part of the thermosphere

where satellites orbit in the thermosphere

direct transfer by electromagnetic waves

the sun

direct transfer by touching

heat from the ground

the transfer by movement of a fluid

heat traveling in the air due to density differences

pressure differences

convention from unequal heating from the earth
