Definitions
Atmosphere
Earth’s protection; broken up into 5 layers; contains gases, solids, and liquids.
process of water vapor cooling & condensing back into liquid.
Condensation
Meteorologist
a person who studies weather and weather and weather patterns.
boundary between two different air masses.
Front
Barometer
– a tool used for measuring air pressure.
Evaportion
the process of the sun heating liquid water and turning it into a gas/water vapor.
coal/gas; naturally occurring fuel formed from dead organisms.
Fossil Fuels
Jet stream
fast moving belts of air in the upper troposphere
slow, or no, movement on an air mass
Stationary Front
Low Pressure System
– low area or low is a region where the air pressure is lower than that of
surrounding locations, associated with poor weather
Runoff
when precipitation moves downhill
water collected underground
Groundwater
Humidity
amount of water vapor in the air.
when a cold air mass pushed underneath a warm air mass forcing it out
Cold Front
High Pressure System
is a region where the atmospheric pressure at the surface of the planet is
greater than its surrounding environment, associated with fair weather
Ozone Layer
part of the stratosphere; absorbs and reflects harmful energy from the sun
evaporation of water off the leaves of plants.
Transpiration
Continental
– related to land, low humidity
when a warm air mass overtakes a cold air mass
Warm Front
Cumulus
is a region where the atmospheric pressure at the surface of the planet is
greater than its surrounding environment, associated with fair weather
Chlorofluorocarbons (CFCs)
chemicals that have the potential to destroy the ozone
state of the atmosphere
Weather
Tropical
warm temperatures due to proximity to the equator
measure of the weight of the Earth’s atmosphere.
Air Pressure
Stratus
– low-laying, layered clouds
