Final answer:
A steep pressure gradient force results in stronger (faster) winds because air moves more rapidly from areas of high pressure to low pressure when the pressure difference is greater. The correct option is c.
Step-by-step explanation:
When there is a steep pressure gradient force (PGF), the result is C) Stronger (faster) winds. This is because a pressure gradient force is the force that moves air from areas of high pressure to areas of low pressure.
The steeper the gradient, or the closer together the isobars (lines of equal atmospheric pressure) are on a weather map, the stronger the force. Thus, winds will be faster as the air is accelerated more by this stronger force.
An example of this effect can be seen in hurricanes, where steep pressure gradients contribute to very high wind speeds. The correct option is c.
