Question

exercise 5
how does the jet stream affect weather around the globe?
carries air in a vertical pattern from the surface of the earth to the top of the clouds.
carries warmer water on the surface of the earth
acts as a river of air, high in the atmosphere transporting warm air and cooler air.
is a band of wind at the surface of the earth carrying water

Explanation:

Jet streams are fast - flowing, narrow air currents in the atmosphere. They are high in the atmosphere (not at the surface) and act like a river of air. They transport warm and cooler air masses. Option 1 is incorrect as jet streams are horizontal (not vertical) air movements. Option 2 is wrong because jet streams carry air, not water. Option 4 is incorrect as jet streams are not at the earth's surface and do not carry water.

Answer:

acts as a river of air, high in the atmosphere transporting warm air and cooler air.
