In a deep lake, how does the hydrostatic pressure at the bottom compare to that at the surface, considering the influence of gravity?

In a deep lake, the pressure at the bottom is higher than at the surface because the weight of the water above pushes down, and gravity pulls that weight toward the lake floor. The increase in pressure is proportional to the depth, the density of water, and the strength of gravity: ΔP = ρgh, where ρ is about 1000 kg/m³ for fresh water, g is 9. 8 m/s², and h is the depth. Thus the deeper the lake, the larger the pressure difference, and the stronger the gravitational pull, the steeper the pressure rise. For example, in a 10‑meter‑deep lake, the bottom pressure exceeds the surface pressure by roughly 100 kPa (about 1 atm), because 1000 kg/m³ × 9.
