What causes two distinct pressure zones between the equator and the poles? . a. the troposphere interacts with the mesophere. b. the ozone layer. c. the fact that nitrogen is heavier than oxygen . d. earth's rotation .

D. Earth's rotation

Explanation:

The Coriolis force, cause distinct pressure zones between the equator and the poles due to the spinning of the earth on its axis. This force directs the winds on the right side in the northern hemisphere and directs them in the left side in the southern hemisphere. This force is the cause and consequence of the earth's internal inertia. Friction force causes it to be actively seen in motion. Compared to other force Coriolis force is smaller and it only deflects the pressure pattern in north and south spheres.  Horizontal deflation is grater near the poles, and less away from poles. The named is given after a French mathematician and physicist Gaspard-Gustave de Coriolis.
