Weather Instrument
This instrument measures temperature
What is a thermometer?
The average air pressure at sea level is this many inches of mercury.
What is 29.92 inches of mercury?
The atmosphere is composed mainly of this gas.
What is nitrogen?
Air masses are large bodies of air that have relatively uniform temperature and this.
What is humidity?
Tornadoes and hurricanes are large areas of this type of pressure.
What is low pressure?
This device measures wind speed/
What is an anemometer?
What is 14.7 lb/in^2
The later of atmosphere where all weather occurs and is closes to Earth's surface.
What is the troposphere?
This type of front is slower than the other main type of front.
What are cold fronts? (Cold fronts are slower than warm fronts?
Air rises when it has this density characteristic.
What is less dense?
This instrument measure atmospheric pressure.
What is a barometer?
What is decreases?
The ozone layer is found in this atmospheric layer.
What is the stratosphere?
This type of pressure is associated with a warm front.
What is low pressure?
At higher elevations, water boils at a lower temperature beacuse of this atmospheric condition.
What is lower air pressure?
This tool helps determine wind direction when reading maps.
What is a compass rose?
The density of our atmosphere does this with an decrease in altitude.
What is increases?
The space shuttle orbits in this atmospheric layer.
What is the thermosphere?
This gas is released into the atmosphere by plants during photosynthesis.
The ozone layer protects Earth by blocking this harmful radiaiton.
What is ultraviolet (UV) radiation from the Sun?
This device carries instruments into the atmosphere to collect weather data.
What is a weather balloon?
Lines connecting points of equal atmospheric pressure are called this.
What are isobars?
Earth's magnetic field traps harmful particles from the Sun into belts of radiation called this.
What are Van Allen Belts?
This gas is removed from the atmosphere by green pants during photosynthesis.
What is carbon dioxide?
In the water cycle, this process occurs when water changes form the liquid to gas due to temperature and pressure conditions.
What is evaporation?
