How We Study Weather
This instrument measures temperature.
What is a thermometer?
When the sun heats the water and turns it from a liquid to a gas (water vapor).
What is evaporation?
Wind moves from areas of high pressure to areas of this.
What is low pressure?
These fluffy, white clouds usually mean fair weather.
What are cumulus clouds?
This is the condition of the atmosphere at a specific time and place.
What is weather?
This instrument measures air pressure.
What is a barometer?
When water vapor cools, turns back into liquid water and forms clouds.
What is condensation?
High pressure usually brings this type of weather?
What is clear or fair weather?
These low, gray clouds can cover the whole sky like a blanket.
What are stratus clouds?
The average weather of a place over many years is called this.
What is climate?
Scientists use data from many tools to predict weather. This person does that job.
What is a meteorologist?
The source of energy that keeps the water cycle going.
What is the sun?
When air sinks, this type of pressure system forms.
What is high pressure?
If you see large, dark clouds in the sky, this type of weather is likely coming.
What is rain?
A large body of air with similar temperature and humidity is called this.
What is an air mass?
Predicting future weather using data and models is called this.
What is forecasting?
When the cloud becomes to full and water falls from the sky in different forms.
What is precipitation?
The greater the difference in air pressure between two areas, the strong this becomes.
What is wind?
Fog is actually this type of cloud that forms near the ground.
What is a stratus cloud?
This is the boundary where two air masses of different temperatures meet, often bringing changes in weather.
What is a front?
If you see weather changing, it's happening in this layer of the atmosphere.
What is the troposphere?
During evaporation, water molecules gain this.
What is heat energy?
During the day, wind blowing from the ocean toward land is called this.
What is a sea breeze?
This energy from the Sun heats the Earth's surface, causing air to rise and clouds to form.
What is solar radiation?
When a cold air mass pushes under a warm air mass, this forms.
What is a cold front?
