This step of the Water Cycle happens when liquid water becomes a gas and rises into the air.
Evaporation.
100
This is a huge area of air that is the same throughout. It takes on the qualities (temperature, water content) of the land or water that it passes over.
Air Mass.
100
This is the study of weather.
Meteorology.
100
This tool measures temperature.
Thermometer
200
True or False: Air is just empty space.
False. Air is made up of tiny invisible particles that have space in between them.
200
When water is a gas mixed with the air, it is called _______.
Water Vapor.
200
This is the place where one air mass pushes into another air mass.
Front.
200
The layers of air that surround the earth are called this.
Atmosphere.
200
This tool measure air pressure.
Barometer
300
This is the weight of air.
Air Pressure.
300
When water that is a gas in the air rises high enough, it begins to cool down and turns back into liquid water droplets. What is this process called?
Condensation.
300
A Front is named for which air mass involved?
The Air mass that does the pushing.
300
The closest layer of air to the Earth is where weather happens. It's called the ______________.
Troposphere.
300
This tool measures the amount of precipitation (we made one in class).
Rain Gauge
400
How does air move? (From an area of ______ to ______)
Air moves from High Pressure to Low Pressure.
400
When condensation happens to water in the air, these form.
Clouds.
400
This is a funnel shaped storm cloud that has a very, very low air pressure inside and causes a lot of damage.
Tornado.
400
These clouds are low, flat sheets that sometimes look gray and often bring precipitation.
Stratus.
400
This tool measures wind speed.
Anemometer.
500
Why do hot air balloons rise?
As air heats up the particles move farther apart/have more space between them. This causes the air in the balloon to be lighter than the air outside of it, so it rises.
500
When water falls down from the sky, it is called this. Also, give 3 examples.
Precipitation: Snow, Rain, Sleet, Hail.
500
Why do thunderstorms happen at a Front? (Think about what happens to the different air masses when they push into each other)
Cold air pushes the warmer air up into the atmosphere causing it to quickly cool down, condense to form huge storm clouds, then as the water builds up in the atmosphere precipitation occurs.
500
This is the name of the scale that rates wind speed based on it's effects.
Beaufort Scale.
500
This device uses radio waves to find the position and speed of storms.
