# Explain why a diver experiences greater pressure when swimming at the bottom of a deep swimming pool compared to just below the surface.

> AQA GCSE Physics (8463) — 4.5.5 Pressure and pressure differences in fluids (Phys only) · Explain · 4 marks

> A diver is training in a swimming pool. She notices that the pressure she feels on her body increases as she swims deeper.

## Mark scheme (4 marks)

1. Pressure in a liquid increases with depth
2. There is a greater (taller) column of water above the diver at greater depth
3. The weight of the water above acts on the diver, producing a downward force / contributing to the pressure
4. Upthrust / pressure difference between top and bottom of the diver is also greater at depth
