GASES
The most abundant gas in the atmosphere
Nitrogen
Where the ozone layer is found
STRATOSPHERE
I am the layer that reaches the highest altitude.
Exosphere
True or false: Pressure at the top of a mountain is less than at the beach
True
Average temperature on earth's surface
15º C
The gas that makes up about 21% of the atmosphere
Oxygen
The layer where weather is found:
TROPOSPHERE
I protect the earth from meteoroids.
Mesosphere
Instrument that measures air pressure
Barometer
This is made up of 3 atoms of oxygen
Ozone
Excess of this gas contributes to global warming
Carbon dioxide
The "hot layer" of the atmosphere
TERMOSPHERE
I extend to an altitude from about 50 km to 80 km.
Mesosphere
This happens to air pressure as altitude increases
The pressure decreases
This is the distance above sea level
Altitude
Gas in the atmosphere that varies from place to place
Water vapour
The layer of electrically charged particles
Ionosphere or termosphere
I am where radio waves are bounced back to the earth's surface.
Ionosphere
Atmospheric pressure to sea level
1013 millibar
It is the amount of water vapour in a specific amount of air
Humidity
Condition of the Earth's atmosphere at a particular time and place:
Weather
My temperature may reach as high as 2000 degrees Celsius.
Ionosphere
My temperature drops about 6.5 degrees Celsius (ºC) per km.
Troposphere
Three units to measure the atmospheric pressure
- Millibar
- Atmosphere
- Pascal
Average temperature on the Earth´s surface without CO2
-18º C
