Vocabulary
Conditions such as rain, clouds and wind
Weather
Wind travels from what pressure to what pressure
What is High pressure to Low pressure
This is the boundary between two different air masses.
What is a weather front?
The process by which liquid water turns into water vapor.
What is evaporation?
This type of pressure system is associated with clear skies and calm weather.
What is a high-pressure system?
Water as a gas
What is water vapor
Wind is created by differences in these two atmospheric conditions.
What are air pressure and temperature
This type of front forms when a cold air mass pushes a warm air mass upward, often causing thunderstorms.
What is a cold front?
The process where water vapor cools and changes back into liquid droplets, forming clouds
: What is condensation?
A cold front is often followed by this type of pressure system, bringing cooler and drier air.
What is a high-pressure system?
An amount of air that moves as a unit
What is air parcel
Creates wind patterns
What is Convection
This front brings light, steady rain as a warm air mass slowly moves over a cold air mass.
What is a warm front?
The step in the water cycle where water falls from clouds as rain, snow, sleet, or hail.
What is precipitation?
Which combination is most likely to result in the formation of large storms? (two things)
What is high humidity and high air temperature
Measure of how hot or cold something is
What is temperature
Warm air rising and cooler air replacing it causes this type of weather
What is thunderstorms
Cold fronts usually bring this type of weather after they pass.
What is cooler and drier weather?
The process by which plants release water vapor into the atmosphere.
What is transpiration?
strong updrafts in a thunderstorm repeatedly lift raindrops into this freezing layer of the atmosphere and cause this type of weather
What is hail
Liquid water droplets suspended in the air
What is a cloud
This large-scale wind system forms over warm ocean waters and can cause heavy rain, strong winds, and flooding.
What is a hurricane?
This symbol on a weather map represents a cold front.
What are blue triangles pointing in the direction of movement?
The movement of water through the ground after precipitation, which replenishes underground reservoirs.
What is infiltration?
warm rises and cool air falls
what is warm air is less dense than cool air
