Wind Formation

Which describes how wind speed is affected by weather?

• Rainy weather causes greater wind speeds.
•  Warmer weather causes greater wind speeds. 
• Differences in air pressure cause greater wind speeds.
• Small temperature changes causegreater wind speeds.

Which has the greatest effect on wind speed?

• precipitation
• cloud cover
• wind direction
• air pressure

Which statement best explains how wind is formed?

• Air is warmed by radiation and airflow increases as a result of the warming.
• Pressure decreases as a result of frictional contact with earth causing air to flow more freely.
•  Unequal heating of the land causes air to flow from areas ofhigher pressure to areas of lowerpressure.

Which best describes why winds at the beach change direction between day and night?

• because the temperatures over land and over water change
• because warm air over land sinksand stays in place over land
• because cool air rises and isreplaced by warm air from the ocean
• because cool air sinks and staysin place over land

Which best describes why wind movement is predictable?

• Air moves from areas of low altitude to areas of high altitude.
• B. Air moves from areas of high pressure to low pressure.
• C. Air moves from areas of low pressure to high pressure.

Which term best describes the type of wind which would most likely be present while playing on a sunny beach during the day?

• hurricane
• land breeze 
• sea breeze

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

Which is most responsible for weather conditions in North Carolina?

• the temperature of the Pacific Ocean
• the ocean temperature at the equator
• the prevailing winds coming from the west
•  the depth of the water in the Gulf of Mexico

Which has the greatest effect on the movement of the jet stream?

• size of clouds
• difference in air temperature
• amount of precipitation

How does the jet stream affect weather conditions around the world?

• The strong wind current of the jetstream pushes weather systems around the world.
• The weak wind current of the jetstream redirects weather systems around the world.
•  The strong wind current of the jet stream prevents weather systemsfrom moving around the world.
