B) winds blowing from west to east along the equator
C) a loss of seasonal variation at high latitudes
D) the elimination of ocean currents

Question

If the Earth's rotation were to reverse, the most immediate and predictable effect would be a change in the direction of prevailing winds. Currently, the Earth rotates from west to east, which contributes to the prevailing westerly winds in mid-latitudes and easterly trade winds in the tropics. A reversal would mean winds would predominantly blow from west to east along the equator, among other changes in wind patterns globally. The length of the year, seasonal variation, and the existence of ocean currents are primarily governed by Earth's orbit around the sun, its axial tilt, and the gravitational pull from the moon and sun, respectively, and would not be directly affected by a change in the direction of rotation.
