# A diver descends from the surface of the sea to a depth of 30 m. Explain why the pressure acting on the diver increases as the diver descends.

> Pearson Edexcel International GCSE Physics (4PH1) — 5.1 Density and pressure · Explain · 4 marks

> Seawater has a density of approximately 1025 kg/m³, which is greater than that of fresh water.

## Mark scheme (4 marks)

1. Pressure in a liquid increases with depth
2. There is a greater weight / more liquid above the diver at greater depth
3. Pressure in a liquid also depends on the density of the liquid
4. Pressure acts equally in all directions / acts at right angles to any surface
