Trade winds blow from the – |
| A. | equatorial low pressure |
| B. | polar high pressure |
| C. | subtropical high pressure |
| D. | subpolar low pressure |
| Answer» C. subtropical high pressure | |
|
Explanation: Wind flows outward down the pressure gradient away from the subtropical highs. As it does so, it encounters the CoriolisEffect caused by the rotation of the Earth. This force causes the winds in the Northern Hemisphere to move from the east towards the west below the subtropical high, and from the west towards the east above the subtropical high. The opposite is true in the Southern Hemisphere. Above the subtropical high winds move from east to west, and below the subtropical high winds move from west to the east. |
