What Is Weather?
Atmospheric conditions at a certain place and time
What is weather?
Amount of water vapor in the air
What is humidity?
Flat, layered clouds found at low altitudes
What are stratus clouds?
Process where liquid water turns into water vapor
What is evaporation?
Large body of air with uniform temperature and humidity
What is an air mass?
Scientist who studies and predicts weather
What is a meteorologist?
Amount of water vapor in the air compared to the maximum it can hold
What is relative humidity?
Fluffy, piled-up clouds that can grow into storms
What are cumulus clouds?
Process where water vapor cools and becomes liquid droplets
What is condensation?
System with sinking air and clear skies
What is a high-pressure system?
Measure of the average kinetic energy of air molecules
What is air temperature?
Temperature at which air becomes saturated and condensation occurs
What is the dew point?
Wispy clouds found high in the atmosphere
What are cirrus clouds?
Water that falls from clouds to Earth’s surface
What is precipitation?
System with rising air, clouds, and precipitation
What is a low-pressure system?
Instrument used to measure wind speed
What is an anemometer?
A cloud that forms at Earth’s surface
What is fog?
Precipitation that forms when snow melts, then refreezes
What is sleet?
Where most evaporation happens on Earth
What are the oceans?
Front formed when cold air pushes under warm air
What is a cold front?
Instrument used to measure air pressure
What is a barometer?
Instrument used to measure relative humidity
What is a psychrometer?
Precipitation that grows larger as it is lifted and dropped by updrafts
What is hail?
Correct order of water cycle stages
What is evaporation → condensation → precipitation → collection?
Intense tropical storm with winds over 119 km/h
