These are visible collections of tiny water droplets or ice crystals in the atmosphere.
What are clouds?
What kind of air can hold the most water vapor-- warm or cold?
What is warm?
What two things are uniform throughout an air mass?
What are temperature and moisture?
What forms when there is an electric discharge between one negative and one positive charged area?
What is lightning?
Draw a symbol for a cold front.
What is a line with triangles on one side?
These fluffy, white clouds look like cotton balls and often mean fair weather.
What are cumulus clouds?
This layer of the atmosphere is where most of Earth’s weather happens.
What is the troposphere?
What words would describe an air mass that forms over water and is cold?
What is a maritime polar?
What scale measures hurricanes?
What is the Saffir-Simpson scale?
This instrument measures air pressure and helps predict weather changes.
What is a barometer?
These thin, wispy clouds form high in the sky and often signal that a change in the weather is coming
What are cirrus clouds?
The process where water changes from liquid to gas and rises into the air.
What is evaporation?
When a warm air mass meets a cold air mass and slowly moves over it, it creates this type of front that often brings steady rain or snow.

What is a thunderstorm?

What is a rain gauge?
These gray, blanket-like clouds cover the sky and can bring light rain or drizzle.
What are stratus clouds?
This effect causes winds and ocean currents to curve due to Earth’s rotation.
What is the Coriolis effect?
When a cold air mass pushes under a warm air mass, causing quick storms, it’s called this.
What is a cold front?
This large swirling storm forms over warm ocean water and has strong winds and heavy rain.
What is a hurricane?
Meteorologists use this technology to track storms, measure rainfall, and detect the movement of precipitation in the atmosphere.
What is radar?
These towering storm clouds can bring lightning, thunder, and heavy rain.
What are cumulonimbus clouds?
This boundary forms where two different air masses meet.
What is a front?
When two air masses meet but neither moves, it forms this type of front that can cause days of cloudy weather.
What is a stationary front?
This scale measures the strength of tornadoes based on the damage they cause.
What is the Enhanced Fujita (EF) Scale?
