Meta Title	9+ Causes of Hydrostatic Pressure: Force Explained
Meta Description	Hydrostatic pressure originates from the weight of a fluid acting upon itself. In a stationary fluid, like water in a lake, the deeper you descend, the greater the weight of the water column above. This accumulating weight exerts a force downwards, creating pressure that acts in all directions. For example, a submerged object experiences pressure from the water not just above it, but also from the sides and below. The pressure increases linearly with depth and the fluid's density.
