A student states the weather is the same as the climate. Which response BEST tells the student the difference between weather and climate?
Weather is about the wind and the rain, but climate is about the clouds.
Weather is the conditions in one day, but climate is the conditions over a long time.
Weather is measured with tools like thermometers, but climate is measured with tools like forecasts.
Weather is recorded on charts, but climate is recorded on world maps.
The local weather station is predicting that a warm front will pass through Charlotte, NC in two days. How will Charlotte’s weather most likely be affected by the passing of a warm front?
The wind speed will increase.
The air pressure will increase.
The temperature will increase.
The Coriolis Effect will increase.
What will most likely happen as a result of the approaching cold front?
It will produce no precipitation.
It will produce some precipitation.
It will produce brief periods of heavy precipitation.
It will produce warm weather.
How will freezing air temperatures most likely affect rain as it falls through the air?
It will change to fog.
It will change to hail.
It will change to sleet.
It will continue to fall as rain.
When a low pressure system moves into North Carolina, which kind of weather willmost likely occur?
cold and dry
fair and sunny
clear and humid
rainy and windy
Which will most likely be the effect on cloud cover when there is a stationary front in an area?
Low, thick clouds will remain in the area while the front remains stationary.
Light, wispy clouds will remain in the area while the front remains stationary.
Light, variable winds will partly clear the skies until the front begins to move.
High winds will blow clouds away, and skies will be clear and sunny until the front begins to move.
A meteorologist predicts that a cold front and a high pressure system will arrive later in the day. Which type of cloud will most likely appear as a result?
fog
stratus
cumulus
cumulonimbus
Which best describes the weather condition in which clouds touch the surface of Earth?
dry
foggy
humid
stormy
A class observes high, feathery clouds during their data collection. Which student’s conclusion is most reasonable?
Bob says the feathery clouds are rain clouds, and it will rain in the next few hours.
Greta says the feathery clouds will remain stationary and bring no rain over the next few days.
Simba says high clouds mean skies are clearing, and there will be sunny skies the next few days.
Horatio says high clouds mean a front is coming and will bring clouds and rain in the next few days.
Which best explains how clouds are classified?
by the elevation at which they are found
by the amount of dust particles in the cloud
by the temperature at which the cloud formed
by how wide the cloud is
Jane wants to measure the amount of precipitation in her backyard for the month of January. Which weather instrument should Jane use?
barometer
rain gauge
weather vane
anemometer
Which causes the subtropical jet stream to bring cold, wet winter weather to the southeastern United States?
El Niño
La Niña
Coriolis effect
Santa Ana winds
Which best explains why North Carolina’s winter weather could vary from what is normally predicted during a La Niña event?
A slight dip in the jet stream could bring colder weather.
Prevailing westerlies will push air masses from west to east.
Cold air from the Gulf Stream could interact with the jet stream and cause winter storms.
Strong surface currents can push hurricane storms away from the North Carolina coastline.
Which conditions are most likely to create a hurricane off the coast of North Carolina?
Cool water temperatures and a tropical storm moving from the northeast.
Cool water temperatures and a tropical storm moving from the southeast.
Warm water temperatures and a tropical storm moving from the northeast.
Warm water temperatures and a tropical storm moving from the southeast.
Which describes the direction of prevailing westerlies?
east to west
west to east
south to west
west to south
A meteorologist noticed an increase of wind speed caused by temperature changes in an upcoming weather pattern. Which best describes why this is happening?
The greater the temperature difference between the air masses, the slower the wind blows in the jet stream.
The greater the temperature difference between the air masses, the faster the wind blows in the jet stream.
The lesser the temperature difference between the air masses, the faster the wind blows in the jet stream.
The lesser the temperature difference between the air masses, the slower the wind blows in the jet stream.
Why do most storms move from the west coast of America to the east coast?
El Niño
La Niña
the jet stream
the polar easterlies
Why do most weather systems in the United States move from west to east?
The West Coast is at a higher elevation than the East Coast, and weather systems go downhill.
Prevailing winds carry weather systems to the east across most of the United States.
The West Coast is warmer, and weather systems move from warmer to colder places.
Mountain ranges prevent the movement of weather systems from east to west.
If there is a jet stream with a cold air mass above it and a warm moist air mass below it, what will the weather be below the jet stream?
cold and dry
cold and wet
warm and dry
warm and wet
Which describes a wind that moves from the land to the sea overnight?
land breeze
sea breeze
trade wind
doldrum
How does a large body of water usually affect weather conditions on nearby land?
It causes the weather to be dryer in the winter.
It causes the weather to be colder in the winter.
It causes the weather to be warmer in the winter.
It causes the weather to be less severe in the winter.
How does the jet stream affect weather conditions around the world?
The strong wind current of the jet stream pushes weather systems around the world.
The weak wind current of the jet stream redirects weather systems around the world.
The strong wind current of the jet stream prevents weather systems from moving around the world.
The strong wind current of the jet stream blows winds from the north to the south.
Which best explains what type of weather the Gulf Stream usually brings to North Carolina?
increased wind speed
increased air pressure
increased temperature
increased evaporation
How could La Niña affect weather during the summer in North Carolina?
It could decrease wind.
It could increase rainfall.
It could decrease rainfall.
It could decrease temperature
Which best describes how winds in the jet stream blow?
no pattern
between two boundaries of hot air
between two boundaries of cold air
between a boundary of cold air and a boundary of hot air
Which conditions will result in high winds?
large differences in air pressure
heavy rains over several days
increase in evaporation rates
presence of cirrus clouds
