<span>When the earth spins in a certain direction, the ocean currents move in the opposite direction, sort of like when a car moves forward you are pulled backwards. However, there would still be wind and the gravitational pull of the moon which causes currents. The rotation of the earth just sort of "accents" these. So as a result, you would have many more smaller ocean current cycles. </span>
It is the C) Spring Balance that is affected by the local force of gravity, since it is the one that has the most movement, therefore it would be difficult to spring.
