Question

Why does the pressure of liquids increases with depth?
What is the possible scientific reason for this?

Answer 1

Water pressure increases with depth because the water up above weighs down on the water below. Pressure can be measured in a variety of ways. Water pressure can be easily calculated with a simple equation involving depth, density and gravity.
Pressure in Liquids
- Its in all directions
- It increases with depth
- It depends on the density of the liquid
- It doesn't depend on the shape of the container.
Pressure = Density $\times$ Gravity $\times$ Height
Pressure =$\rho \left(rho\right)\times g\times h$
Water, like all things on Earth, is pulled downward by the force of gravity. Every body of water has a certain weight, and this weight pushes downward on whatever is below it. Water pressure is the result of the weight of all the water above pushing down on the water below. As you go deeper into a body of water, there is more water above, and therefore a greater weight pushing down. This is the reason water pressure increases with depth. The pressure depends only upon the depth, and is the same anywhere at a given depth and in every direction.
