Question & Answer
Choose the Best Answer
The pressure gradient force acts opposite to gravity, causing water to rise.
Gravity pulls water down, while the pressure gradient force equalizes pressure at different depths.
Both forces cancel each other out, resulting in no movement of water.
The pressure gradient force is negligible compared to gravity, having no impact on water flow.
Understanding the Answer
Let's break down why this is correct
Gravity pulls the water downward, creating higher pressure at deeper levels. Other options are incorrect because Some think the pressure gradient pushes water upward, raising it; It sounds like both forces cancel so nothing happens.
