Pressure gradient is a measure of _______________.
AI Explanation
The correct answer is C) pressure difference over horizontal distance.
The pressure gradient is a measure of the change in pressure over a given horizontal distance. It is the rate of change of pressure with respect to the distance in a particular direction, usually horizontally. A higher pressure gradient indicates a more rapid change in pressure over that distance.
The other options are incorrect because:
A) Vertical pressure variation is not the definition of pressure gradient.
B) Pressure difference over time is not the definition of pressure gradient.
D) A high-pressure area is a region of high pressure, not a measure of the pressure gradient.
