Explain why pressure in a liquid increases with depth Explain your answer using Pressure in liquids (physics only) and depth.

Pressure in a liquid increases with depth because the weight of the liquid above exerts a force on the liquid below. As depth increases, there is more liquid above, which increases the weight and therefore the pressure at that depth.

A strong answer should address (Physics only) Identify density in kilograms per metre cubed and depth in metres when using p = hρg directly. Use the context of Pressure in liquids (physics only) within Pressure and pressure differences in fluids (physics only), then state the relevant forces or motion reasoning with units where needed. The answer is correct when it names the key physics quantity, keeps force and pressure distinct, and links the conclusion back to the approved learning objective.
