the most abundant gas in the atmosphere
nitrogen
100
the layer where weather is found

100
What weather instrument is used to measure the amount of weather vapor in the air or humidity
hygrometer
100
True or false: Air pressure increases as you increase altitude.
False: Air pressure decreases because the air becomes less dense as you go up the layers of the atmosphere
100
the layer of gas that surrounds the planet
atmosphere
200
the gas that makes up about 21% of the atmosphere
oxygen
200
layer of atmosphere where the ozone layer is found
stratosphere
200
This instrument measures how hot or cold it is
thermometer
200
True/False: When you compress gases you release pressure surrounding the gas. 
True
200
a person who studies and tries to predict the weather
meteorologist
300
excess of this gas that is a mix of carbon and oxygen contributes to global warming
carbon dioxide
300
the "hot layer" of the atmosphere
thermosphere
300
This instrument is used to measure air pressure
barometer
300
True/False: Air pressure decreases as altitude increases.
True
300
the transfer of thermal energy by touch or contact
conduction
400
gas in the atmosphere that makes up the ozone
oxygen
400
the layer of electrically charged particles called ions
ionosphere
400
An instrument that measures wind speed
Anemometer
400
True/False: As the density of air increases, the air pressure remains the same. 
False: It decreases

500
An instrument that measures wind direction
