Water pressure at the bottom of the ocean arises from the weight of the overlying water. Does this mean that the water exerts pressure only in the downward direction? Explain.

Short Answer

Expert verified
No, the water at the bottom of the ocean does not exert pressure only in the downward direction. It exerts pressure equally in all directions, as per Pascal's Principle.

Step by step solution

01

Fundamental Understanding of Pressure

Pressure in fluids, such as water, is not dependent on direction. It might seem logical to assume that water pressure at the bottom of the ocean only applies downward due to the weight of the water above, but pressure exerted by fluids is actually exerted equally in all directions.
02

Understanding Fluid Statics

The principle of fluid statics, also known as Pascal's Principle, states that changes in pressure at any point in an enclosed fluid at rest are transmitted undiminished to all points in the fluid and act in all directions. Therefore, the pressure at the bottom of the ocean is exerted not just downward but in all directions.
03

Interpretation of the Phenomenon

If you were to stand at the bottom of the ocean (assuming you could withstand the incredible pressure), you would feel this pressure from all sides, not just from above. This is because the water pressure is exerted in all directions, not just downward.
