Describe the air that exists in a low pressure air mass.
What is "warm and moist"?
200
Explain the difference between climate and weather.
What is "Climate is an AVERAGE weather pattern over long periods of time and weather is the state of atmosphere at a given place and time"?
200
Describe temperature patterns along the equator.
What is "steady, warm temperatures all year long"?
200
These are called "thunderstorm clouds".
What is "cumulonimbus"?
200
Which general direction would a balloon travel when released in middle America? Toward the Pacific ocean (west) or Atlantic ocean (east)?
What is east, toward the Atlantic coast.
300
Scientists look at these two indicators to determine if an area is suffering a DROUGHT.
What are 1. rainfall and 2. lake/river water levels.
300
What is a Jet Stream?
What is "the strong wind current that pushes weather systems around the world"?
300
What is El Nino? (where, what temperature, what does it affect?)
What is "The water in the Pacific Ocean gets warmer than normal, and the flow of the jet stream is disrupted."
300
These cloud look like puffy cotton balls. Flat base, with rounded towers. What type of weather is typical with these clouds and what is the name?
What is "Cumulus clouds--often called "fair-weather clouds"?
300
What determines the direction in which air masses flow across the United States? A. the Gulf of Mexico B. the Atlantic Ocean C. the heat from the sun D. the rotation of Earth
What is "D rotation of the Earth"?
400
What will be the effect of a warm front moving into the area?
What is "light precipitation and then clear skies as the front moves out."
400
Explain the steps in the water cycle.
What is "precipitation, run off, evaporation, condensation (clouds) and back to precipitation"?
400
What causes the winds at the beach?
What is "differences in the temperature of land and ocean"?
400
Which type of weather would most likely accompany dark nimbostratus clouds?

400
Weather Conditions • Cold front moving in behind warm, moist air • Heavy, constant winds • Sudden hail • Unstable atmosphere Which type of severe event is most likely to occur during these weather conditions?
What is "tornado"?
500
When a low pressure system moves into North Carolina, which kind of weather will most likely occur? A. cold and dry B. fair and sunny C. clear and humid D. rainy and windy
What is D: rainy and windy.
500
Describe the Coriolis Effect.
What is "since the Earth rotates, the Coriolis force deflects these winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. In the Northern Hemisphere, this deflection causes the wind flow around high pressure systems to go clockwise while flow around low-pressure systems travels counterclockwise."
500
Which causes North Carolina to experience an increase in winter precipitation? A. El Niño B. La Niña C. trade winds D. prevailing westerlies
What is "A: El Nino"?
500
What are 3 most important factors to cloud formation?
What is "proper temperature, proper amount of water vapor, change in air pressure"?
500
Which is most likely to happen when a tropical storm moves from the coast of Africa toward the United States, and water temperatures increase?
What is "continue moving westward and gain intensity"?
