the layer of air that surrounds our planet
|
|
|
air pressure
|
particles of air pressing down on earths surface
|
|
|
troposphere
|
the layer of atmosphere closest to the earth
|
|
|
stratosphere
|
the layer of atmosphere that contains ozone and is located above the troposphere
|
|
|
greenhouse effect
|
the warming of earth caused by the atmosphere trapping thermal energy from the sun
|
|
|
air mass
|
a huge body of air which all has similar temperature and moisture
|
|
|
front
|
the border where two air masses meet
|
|
|
barometer
|
an instrument that measures air pressure
|
|
|
humidity
|
the amount of water vapor in the air
|
|
|
anemometer

|
|
4 layers of earths atmosphere
|
mesosphere, stratosphere, troposphere, and thermosphere
|
|
|
two properties of air masses
|
temperature and moisture
|
|
|
layer of atmosphere where weather occurs
|
troposhere
|
|
|
characteristics of warm air
|
heat (temperature) and humidity (moisture content)
|
|
|
cold front - what it is and what happens during and after
|
forms when cold air mass catches up to a warm air mass. The cold air mass forces the warm air up into the atmosphere. As the warm air is pushed up, it cools and forms clouds. Rain and thunderstorms occur.
|
|
|
how does air pressure change as air masses move over an area?
|
as a front moves closer, air pressure drops. As the front moves over the area, air pressure rises.
|
|
|
thermometer
|
measures the temperature of air
|
|
|
weather vane
