In a fluid, what happens to pressure as depth increases?

In a fluid, pressure increases with depth due to the weight of the fluid above exerting force on the fluid below. When you are submerged in a fluid, each layer of fluid adds to the overall pressure experienced at a certain depth. This is described by the hydrostatic pressure formula, which states that pressure at a given depth is equal to the pressure at the surface plus the weight of the fluid column above it divided by the area it acts on. As more depth means more fluid weight is pushing downward, pressure correspondingly rises. This concept is fundamental in understanding fluid dynamics and is often observed in practical scenarios, such as diving underwater or measuring water pressure at varying depths.
