Tools
What instrument is used to measure temperature?
thermometer
What unit is temperature measured in?
degrees Fahrenheit or degrees Celsius
What happens to air pressure as a balloon rises?
It gets less.
Why is it important for meteorologist to record weather daily?
To help identify patterns.
**This helps us predict future weather and tells us if our weather is stable or not.
When air is trapped inside a syringe and you put pressure on it what is happening?
Air particles are getting closer together.
What instrument is used to measure air pressure?
barometer
How is humidity recorded?
As a percentage
As a balloon gains altitude, there are fewer particles on the outside of the balloon, so there is less pressure and the air inside the balloon does what?
expands
What is severe weather?
Weather that is dangerous or causes damage.
Do air particles expand inside a syringe?
No.
What instrument is used to measure wind direction?
wind vane
Wind speed is measured in what unit?
km/h or m/hr
Why does a balloon on the ground have more pressure?
The air is denser and has more particles pushing on the balloon. As it rises there are less particles pushing against it.
How are tornados and hurricanes alike?
Both form when warm air rises and begins to rotate. Both have strong destructive winds.
Is air matter?
Yes
What instrument is used to measure humidity?
hygrometer
How is wind direction described?
north south east west
Why does a balloon that gets too high pop?
The air on the inside continues to expand when there is less air pressure on the outside.
What is meteorology?
The study of the Earth's weather.
After blowing up a balloon does it weigh more?
Yes
What instrument is used to measure wind speed?
anemometer
How is air pressure recorded?
millibars
How many layers is the Earth's atmosphere?
5
What is a weather forecast?
A prediction of the Earth's weather.
Where do we find air?
All around us.
