Evacuation
Action taken as a devastating storm approaches, when people are asked to leave the area for their safety.
Storm surge
Usually high rises in the level of the ocean during a hurricane.
Salinity
Concentration of salt in the environment
Gusts
Sudden increase in the wind velocity
Can hurricanes create tornadoes when they hit land?
Yes
Do hurricanes redistribute heat from tropical oceans over land?
Yes
What distinguishes a hurricane from a thunderstorm?
Gusty winds
Water damage from a hurricane is often more destructive than wind damage. Why?
Water can be very destructive and a hurricane can cause flooding.
How can people prepare for a hurricane?
Evacuate homes, board up windows, stock storm supplies.
What is the relationship between an increase in the speed of moving air or water and the force the wind or water exerts?
If the speed doubles (2x) the force quadruples (4x)
Why do hurricanes eventually die over land?
They are cut off form the warm ocean water, and friction is increased causing the storm to loss energy.
How do storms damage the marines ecosystem?
Salt and mineral content of a part of the ocean may change, shallow water creatures can be damaged.

The force of wind hitting a building depends on what?
The speed of the wind
Which hurricane-caused phenomenon is responsible for the most deaths during a storm?
storm surges
What is one way in which thunderstorms and hurricanes differ?
hurricane winds spiral, thunderstorm winds blow in a straight line
What are some problems caused by hurricanes?
spread of infectious diseases, damage to crops, and interruption of water supply
What is one benefit of storms?
provide water for plants and animals.
What causes the most physical damage from a hurricane?
wind and water
What are some problems caused by hurricanes?
spread of infectious diseases, damage to crops, and interruption of water supply
What is one way in which thunderstorms and hurricanes differ?
hurricane winds spiral, thunderstorm winds blow in a straight line
What happens as a hurricane approaches land?
The energy from the wind is transferred to the shallow waters and creates waves.
What threat does a hurricane pose to areas far inland?
smaller storms, such as tornadoes can spin off and cause damage.
