The curved movement of air or water is the result of which of these?
Select one:
a. winds spinning off the equator
b. the rotation of Earth on its axis
c. the different air movements north and south of the equator
d. the friction that slows down winds near Earth’s surface

Answer;

B. the rotation of Earth on its axis

Explanation;

• The Coriolis effect describes how the Earth's rotation steers winds and surface ocean currents. The Coriolis effect causes the motion of a freely moving object to appear as a curve.
• Therefore, since air and water move freely, the Coriolis effect makes their movement to be curved. This is why the movement of winds and oceans  does not follow a straight line but it is bent and curved.
