What is a hurricane?
A severe storms with a low pressure center and winds over 74 miles per hour
What should you do during a Tornado to protect yourself?
Go to the middle of the ground floor and stay away from windows
What is climate?
The long term weather conditions of an area
Ms. Downey breathed against a window and noticed that her breath made a spot on it from the water vapor in her breath. Which stage of the water cycle would this show?
Condensation
What is humidity?
the amount of water vapor in the atmosphere
TRUE OR FALSE: Cool ocean currents cool air masses above them.
TRUE
What is a tornado?
A rapidly spinning column of air traveling from a thunderstorm to Earth's surface
Which two consequences can a severe storm such as a hurricane bring?
A. severe flooding that can contaminate drinking water B. lack of necessary clothing from hurrying to pack

A and D
What is condensation?
the change of state from a GAS to a LIQUID
What is main source of energy for the water cycle?

What is dew point?
The temperature at which condensation begins
What are the 3 ways water enters the atmosphere?
Evaporation, Transpiration, Respiration
What is a weather front?
The boundary where two air masses meet
How does the Earth's tilt effect temperatures in a region? Think about the different seasons.
Summer time - Northern hemisphere has warmer temperatures
Winter time - Southern hemisphere has warmer temperatures
What is a storm surge?
A "dome" of water that sweeps across the coast where a hurricane hits
How does Earth's atmosphere insulate the planet and protect life on Earth? Think about unit 1 and 2.
The different layers in the atmosphere absorb and reflect the sun's energy back into space. This keeps our planet and life from getting too hot.
