100
What is an air mass?
A body of air with constant temperature and water vapor
100
Name 4 types of severe weather
tornados, hurricanes, thunderstorms, blizzards, drought
100
What does a barometer measure?
air pressure
100
What is climate?
Average of weather conditions over a long period of time, usually 30 years
200
In what layer of the atmosphere is most of Earth's air and weather?
The troposphere
200
Where does a front form?
Between air masses
200
How does a tornado form?
Different layers of air move at different speeds or in different directions
200
How do forecasters use weather maps?
To show current conditions and their predictions
200
Name two things that can affect climate?
Volcanos, meteorite and asteriods, burning coal and gasoline
300
What happens when cold air is next to warm air?
The cold air sinks and the warm air rises
300
What are the three main kinds of fronts?
Warm front, cold front, and stationary front
300
Where does a hurricane form?
Over warm ocean waters
300
Name 3 weather measuring tools
Barometer, anemometer, rain gauge, thermometer, radar, hygrometer
300
How do fossils help scientists make assumptions about past climates?
By comparing the fossil to a modern day organizsm, scientists can tell what the climate in that area used to be like
400
What causes wind?
Convection currents and spinning of Earth
400
What are the four basic kinds of air masses?
Continental polar, continental tropical, maritime tropical, maritime polar
400
Name three parts of a weather system
temperature, moisture, clouds, precipitation, air pressure, wind speed, and wind direction.
400
What does the capital H indicate on the weather map, and what will the conditions in that area likely be?
Area of high pressure; clear skies
400
How do ocean currents affect climate?
They make climates cooler or warmer than they would be otherwise
500
How is the jet stream formed?
By different temperatures between convection currents
500
What is the difference in precipition between a cold front and a warm front?
A cold front has heavy but brief precipition, while a warm front has slow moving clouds and longer periods of precipition
500
What is lightning?
a large electrical spark moving between areas of opposite electrical charge
500
How do forecasters make predictions on what the weather will likely be in the future?
By making inferences on how air, land, and the steps of the water cycle interact
500
How might the climate on one side of a mountain be different than the climate on the otherside of the mountain?
One side of the mountain will have a wet climate while the other side will be drier because of a rain shadow
