Multiple Choice

Thunderstorms are more common in some areas than in others. The map shows the average number of thunderstorms per year in different parts of the United States.

Why are there significantly more thunderstorms in Florida than in California?

• The air in Florida is more stable than the air in California.

• The state of Florida is smaller than the state of California

• The air above Florida holds less moisture than the air above California.

• The ocean currents near Florida are warmer than the ocean currents near California.

Multiple Choice

All hurricanes must have an energy source to form and grow. From where does this energy come?

• The Earth's rotation on its axis

• High air pressures

• Warm air rises and pulls cooler air is pulled into it
