A way to tell how much heat energy is in matter
Temperature
Forms of energy that transfers because of temperature differences
Heat
Heat transfer from one object to another
Radiation
Transfer of heat from one object to another
Conduction
The transfer of heat energy due to the circulatory motion of a gas or liquid
Convection
water vapor gas rising high into the air cooling and changing into a liquid or ice
Condensation
This is when the heat absorbs by the green house gases In Re-Radiated back to the Earth
Green House
Carbon dioxide and water vapor
Green house gases
bodies of air with nearly the same temperatures and humidity, they can be 1,000’s of miles across the earth and as high as the stratosphere
Air masses
Air that does not rise and therefore causes stable, nice weather
Stable air mass
airthat rises easily and can formcloudsandrain
Unstable air mass
the movement of warm air upward and cool air downward due to the uneven heating of the earth’s surfaces.
Convection Current
the moving part of convection current
Wind
the flow of air from a body of water to the land due to the uneven heating of water and land (Daytime)
Sea Breeze
the flow of air from the land to a body of water due to the uneven heating of water and land (nighttime)
Land Breeze
(air pressure) the force that air puts on everything on earth. The amount of pressure depends on the sun’s energy.
-pressure goes down as you get higher in the atmosphere
Atmospheric Pressure
another name for atmospheric pressure
Barometric Pressure
an instrument that detects and measures air/atmospheric pressure changes
Barometer
visible masses of billions of tiny droplets of water or ice crystals that have condensed around small particles in the atmosphere
Clouds
water in a gas state
Water Vapor
usually leads to clouds and rain.
Low pressure “L”
clear skies
High Pressure “H”
a boundary separating two masses of air of different temperatures and humidity, and is the main cause of bad weather
Weather Fronts
