Air Pressure 1
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?
Warm air is ...
less dense
The amount of water Vapor in the air
Humidity
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
Another name for air pressure
Barometric Pressure
Weather Happens in this layer of the atmosphere
Troposhere
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
An instrument that measures air pressure and contains mercury
Barometer
Meteors burn up in this level of the atmosphere
Mesosphere
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
When air pressure rises...
Weather gets better
The layers of air around the Earth; held in place by gravity
Atmosphere
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
An instrument that measures air pressure and does not contain mercury
Aneroid Barometer
the heat energy from the sun, that heats up water on Earth's surface, causing it to evaporate and turn into water vapor.
Radiation
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 it is located between 2 other layers we have learned about
Ionosphere
a cloud that forms at the lowest altitude; along the surface of the ground
Fog
When air pressure is falling....
weather gets worse
This is a person who studies and tells about the weather.
What is a meteorologist?
