the air that makes up the atmosphere & exerts pressure on objects from all directions
Air pressure
Weather patterns over a long period of time ( years )
Climate
The outer most layer
Exosphere
This is a group of tiny water droplets in the sky.
What are Clouds?
This tool measures the density of liquids
Hygrometer
air mases that form over northern Canada, and cause the thermometers to nose dive ( super cold)
Continental Polar
Thick or crowded; cold air
Dense
long periods of no rainfall
Drought
this is the coldest layer
Mesosphere
these clouds are puffy with a flat bottom, they bring fair weather
Cumulus
This tool measures wind speed
Anemometer
Forms when a mass of warm air advances and rises over a retreating mass of cold air.
Warm Front
areas of no air , so no air pressure
Vacuums
the cooling process by which a gas changes back into a liquid
condensation
This layer is the hottest at temps over 2700*F
Thermosphere
these clouds form a huge dark vertical piled tower, they bring thunderstorms
cumulonimbus
A boundary between air masses with different temperatures
Fronts
air masses occur in the summer and form over Mexico. They bring hot air to the southwestern states.
Continental Tropical
metric units of measure, on a barometer
millibars
The heating process by which a liquid changes into a gas
Evaporation
The ozone is located in this layer
Stratosphere
These are featherlike clouds with ice crystals
Cirrus
Forms when a mass of cold air advances to displace a mass of warm air
Cold Front
air masses form over the ocean near the equator
Maritime tropical
a large body of air with similar temps and air pressure
air mass
process in which plants give off water through their Stomata
Transpiration
This is the layer where weather happens
Troposphere
these clouds are spread out in a blanket like layer
Stratus
air masses that form over the Pacific ocean and the North Atlantic ocean. they carry cool moist air.
Maritime Polar
When a warm air mass encounters a cold air mass and no movement occurs
Stationary Front
what are the 4 elements weather depends on
Temperature, Wind, Air pressure, Precipitation
the process of water soaking into the ground
infiltration
This layer is where the Aurora is located
Ionosphere
a cloud that forms at the lowest altitude; along the surface of the ground
Fog
This is a person who studies and tells about the weather.
What is a meteorologist?
when a cold front, closely following a warm front, finally over takes the warm front
Occluded Front
