Tim said that Chicago is most likely to experience rainy weather. Jennifer thinks that Dallas is most likely to experience rainy weather.
Which student is correct?
Tim because Chicago is the closest to a low pressure system and they produce precipitation.
Jennifer because high pressure systems produce precipitation
Both students are correct because all systems produce precipitation
Neither of the students are correct because the cities are not close enough to the system.

Scientists say that conditions must be "just right" for a hurricane to start up. Which is the first step of "just right" in the development of a hurricane?
Cool ocean water replaces warmer surface water
Very warm ocean water evaporates into the atmosphere
Hot dry wind blows from land across the ocean surface
Humid ocean air cools and condenses to form precipitation
Thunderstorms are the result of which type of pressure system?
Low
High
Why do hurricanes form more often at the end of summer?
The ocean water is cooling off and creating more moisture in the air.
The ocean water is cooling off and creating less water vapor in the ocean.
The ocean water is much warmer which fuels the water cycle and creates lower air pressure.
The ocean water is much warmer which fuels an increase in water vapor on the ocean's surface.
Where do Hurricanes form?
NEAR the Equator
Away from the Equator
NEAR the North/South Poles
