This tool measures air pressure.
What is a barometer?
This type of cloud often brings thunderstorms.
→ What is a cumulonimbus cloud?
Weather occurs in this lowest layer of the atmosphere.
→ What is the troposphere?
This type of front forms when cold air pushes under warm air.
→ What is a cold front?
These winds blow over long distances across Earth.
→ What are global winds?
This is a prediction of future weather conditions.
→ What is a weather forecast?
This instrument measures wind speed.
→ What is an anemometer?
These high clouds are mostly made of ice crystals.
→ What are cirrus clouds?
The ozone layer is found in this layer.
→ What is the stratosphere?
This front occurs when neither air mass moves.
→ What is a stationary front?
This breeze blows from sea toward land during the day.
→ What is a sea breeze?
This alert means conditions are right for severe weather to happen.
→ What is a watch?
This tool measures rainfall amounts.
→ What is a rain gauge?
This low, wide cloud layer brings steady gray skies.
→ What are stratus clouds?
This is the third and coldest layer of the atmosphere.
→ What is the mesosphere?
Clear and dry weather is usually linked to this system.
→ What is a high-pressure system?
This breeze blows from land to sea at night.
→ What is a land breeze?
This alert means severe weather has already been seen or detected.
→ What is a warning?
This instrument measures air temperature.
→ What is a thermometer?
This rotating column of air touches the ground.
→ What is a tornado?
This outermost layer is closest to space.
→ What is the exosphere?
Stormy and wet weather is often associated with this system.
→ What is a low-pressure system?
During this climate pattern, Pacific Ocean waters warm.
→ What is El Niño?
Hurricanes and typhoons are this type of storm occurring in different locations.
→ What are tropical cyclones?
Weather balloons collect data about temperature, pressure, and this invisible gas in the air.
→ What is humidity (water vapor)?
These two things are found in all thunderstorms.
→ What are lightning and thunder?
The internationally recognized boundary between Earth’s atmosphere and space is called this.
→ What is the Kármán line?
A cool, dense air mass usually has this type of pressure.
→ What is high pressure?
Wind is caused by differences in this.
→ What is air pressure?
A strong snowstorm with high winds is called this.
→ What is a blizzard?
This tool shows the direction from which the wind is blowing.
→ What is a wind vane?
Ice falling in balls or lumps from a storm cloud is called this.
→ What is hail?
This layer protects life on Earth by absorbing harmful ultraviolet radiation.
→ What is the stratosphere?
A boundary between two air masses is called this.
→ What is a front?
The amount of water vapor in the air compared to how much it can hold is called this.
→ What is relative humidity?
Scientists who study weather are called this.
→ What are meteorologists?
