Which statement is false? (a) Pressure gradient is the difference in pressure between high and low pressure areas. (b) Wind speed is directly proportional to the pressure gradient. (c) This means the weakest winds are in the areas where the pressure gradient is the greatest.

option B

Explanation:

Pressure gradient is the difference in the pressure between two areas in the surrounding.

so, option A is true.

Pressure is inversely proportional to wind.

If pressure of an area increases velocity of the wind decrease or pressure of the area decreases wind speed increases.

So, option C is true.

hence, the False answer is Wind speed is directly proportional to the pressure gradient.

So, the correct answer is option B
