EARTH'S ATMOSPHERE
The atmospheric layer where weather occurs
What is the troposphere
High, wispy clouds
What are cirrus clouds?
The units used to measure air pressure
What are millibars?
The amount of mass in a given volume
What is density?
Where very high altitude cirrus clouds and jet planes may be found in this layer
What is the stratosphere?
Puffy clouds
What are cumulus clouds?
An instrument that measures air pressure
What is a barometer?
We know the wind will always blow...
What is "away from high pressure and toward the low?"
The gaseous form of H2O
What is water vapor?
In the troposphere, as altitude increases, this happens to temperature
What is decreases, or goes down?
This word indicates dark, rain-filled clouds
What is nimbus?
This happens to air pressure as a warm front moves in?
What is the pressure steadily decreases?
The investigation in which the flask of air was put into hot water and the balloon inflated, shoed that this quantity does not change, even if temperature changes.
What is the mass?
This happens when the temperature of an air mass increases
What is, the air mass rises higher in the atmosphere, causing lower air pressure on the earth below it.
Differences between areas of high pressure and low pressure in the troposphere
What causes wind?
Clouds that form blanket-like layers
What are stratus clouds?
This is caused by dense air pressing down on the surface of the Earth
What is high pressure?
This often occurs at fronts
What is precipitation?
The condition of the earth's atmosphere at a particular time and place
What is weather?
When wind is blowing from one area to the next,...
The wind will blow from an area of low pressure to an area of high presure.
These clouds are often called thunderheads, and lead to heavy rainfall.
What are cumulonimbus clouds?
The difference in pressure between two areas, divided by the distance between the two areas
What is the Pressure Gradient Force?
This symbol indicates a cold front moving in.
What is a line of blue triangles?
