Work
Water evaporating from earth’s surface and falling again in rain or snow to be collected by the land, rivers, lakes, and rocks to flow back into the ocean
The significant aspect of weather patterns
Has strong influence on climate
Thermal Energy
Can only be transferred by means of currents in air, water, or other fluids
Thermal Energy
Used to model patterns of atmospheric movement and can be used to make predictions of future weather
Weather maps
body of air that has about the same temperature and humidity throughout
Air Mass
measure of weight of the atmosphere on a given area of the surface of the Earth; barometric pressure
Air Pressure
instrument to measure wind speed
Anemometer
an envelope of mixed gases is held to the Earth by gravity
Atmosphere
When temperature differences cause liquids and gases to expand and move
Convection Current
The effect of Earth’s rotation on the path of air and water; causes the path to curve
Coriolis effect
amount of water vapor present in the air
Humidity
Narrow band of high speed wind high in the atmosphere; moves west to east in the Northern Hemisphere
Jet Stream
global wind located at mid-latitude
Prevailing winds
instrument used to measure humidity in the air Psychrometers
Psychrometers
an area where two air masses with different temperatures and pressures meet
Weather front
heat flow and movement of material within the earth
earth quakes volcanic eruptions and form mountains
matching coastlines and similarities in rock types and life forms suggest
One continent
used to interpret Earth’s features and predict future changes
Topograhic maps and satelite images
earth’s features change due to what
weathering erosion deposition
