How are the prevailing winds set up? a. earth's rotation sets up a general circulation pattern from the poles to the equator. uneven heating breaks it into six cells and deflects the surface winds. b. uneven heating sets up a general circulation pattern from the poles to the equator. earth's rotation breaks it into six cells and deflects the surface winds. c. uneven heating sets up a general circulation pattern from the equator to the poles. earth's rotation breaks it into six cells and deflects the surface winds. d. earth's rotation sets up a general circulation pattern from the equator to the poles. uneven heating breaks it into six cells and deflects the surface winds.
