Atmoshphere & air pressure
what the lower atmosphere (or troposphere) is like at any given place and time
weather
air that moves horizontally
wind
the changing of a gas into a liquid
What is condensation
a cloud at ground level
What is fog
A cold air mass that is moving can quickly push up a warm air mass.
What is a cold front?
the force put on a given area by the weight of the air above it
What is air pressure
a wind that blows from the sea toward the land
sea breeze
a comparison between how much water vapor is in the air and how much the air could hold at a given temperature
What is relative humidity
any form of water particles that falls from the atmosphere and reaches the ground
What is precipitation
a boundary between air masses with different temperatures
What is a front?
the air that surrounds the earth
atmoshphere
a wind that blows from land toward the water
land breeze
the water that is in the air
water vapor
a type of cloud that forms in blanketlike layers
What are stratus clouds
a large region of the atmosphere where the air has similar properties throughout
What is air mass?
this instrument measures air pressure
barometer
the curving of the path of a moving object caused by Earth's rotation
Coriolis effect
the changing of a liquid into a gas
evaporation
a cloud collection of water droplets or ice crystals in the suspended air
what is a cloud
when warm air moves in over a cold air mass
What is a warm front
the layer closest to Earth's surface
troposphere
sinks slowly down
high-pressure system
the amount of water vapor in the air
What is humidity
what are types of precipitation
rain, snow, hail, sleet
