The jet stream usually stays too far north to affect Florida’s weather. What is the jet stream?

• The spinning of the air in the same direction as Earth’s rotation

• The spinning of the air in the opposite direction of Earth’s rotation

• The movement of air from an area of high pressure to an area of low pressure

• A narrow band of strong winds that blow in the upper region of the atmosphere

What impact does the Gulf Stream have on the climate of the east coast of the US?

• The cold water from the Gulf Stream current cools the land.

• The warm water from the Gulf Stream current warms the land.

• The cold water from the Gulf Stream current decreases inland wind speeds.

• The warm water from the Gulf Stream current increases inland wind speeds.
