altitude
height above the earth's surface
barometer
instrument used to measure air pressure
thermosphere
layer of the atmosphere above the mesosphere where temperatures are the highest in the atmosphere
stratosphere

convection
process of heat transfer by the circulation or movement of a liquid or a gas
what do differences in density cause the air to do
rise or sink
what forms are matter
solid, liquid or gas
what supplies the atmospheres energy
sun
mesosphere
the layer of the atmosphere just above the stratosphere; burns up most meteors
respiration
the process by which oxygen combines with food to release energy and carbon dioxide

conduction
the transfer of heat between two stationary entities
radiation
transfer of heat or energy through rays of various wavelengths
air pressure decreases as you move higher in atmosphere
true
