• cyclone
• hurricanes

Tornadoes can occur throughout the United States. One area where most of the tornadoes occur is known as Tornado Alley. Which environmental factors MOST likely impact the formation of tornadoes in this area?

• High pressure systems colliding with high pressure systems

• cold dry air and warm dry air moving toward each other

• low evaporation rates and windy conditions

• cool dry air colliding with warm moist air

The air masses that interact to form hurricanes and cyclones rise and fall due to changes in

air density and air pressure. Why do these storms also spin?

• Ocean currents drag the air above them in circles.

• The Moon’s gravity pulls air currents with the tides.

• Low-pressure air pushes high-pressure air sideways.

• Earth’s rotation causes the air to turn as it moves north.

What causes the differences in the air masses that permit hurricanes to form over oceans?

• Ocean water is cool and cools the air above it.

• Ocean water is warm and heats the air above it.

• Ocean water contains salt that reacts with air, changing the air pressure.

• Ocean water contains algae that make oxygen, changing the air’s composition.

The high winds and torrential rains of a hurricane can cause damage to cities and natural

areas in its path. A hurricane is likely to gain the MOST strength when it travels over which

of the following?

• cool ocean

• inland area

• salty ocean

• warm ocean

How do hurricanes form and move

• The storms form at the equator and initially move east.

• The storms form at the equator and initially move south.

• The storms form at the equator and move west then north.

• The storms form at the equator and moves west then south.

Thunderstorms and hurricanes are examples of severe weather.

Which of these weather conditions is necessary for the formation hurricanes?

• A cold rain falling to the ground

• air masses combining to create an area of high pressure

• winds spiraling downward and away from the center of the storm.

• An area of low pressure feeding warm moist air upwards into the storm.

Which of the following storms is the most commonly produces tornadoes?

• Single Cell

• Multi Cell Cluster

• Supercell

• Multi Cell Line

As the air pressure decreases in a hurricane, what would happen?

• The storm will get larger

• Wind Speed will increase

• The eye wall of the hurricane would form

• The hurricane would lose power
