How does the pressure at a certain depth in water differ from that of the same depth in river water. Explain year answer.

Explanation

To understand how the pressure at a certain depth in water differs from that of the same depth in river water, we need to consider the factors that affect fluid pressure.

### Step-by-Step Solution:

1. **Understanding Fluid Pressure**:
- Fluid pressure at a certain depth is determined by the weight of the fluid above that depth. The formula for pressure (P) at a depth (h) in a fluid is given by:
\[
P = \rho g h
