A pressure gauge is lowered into the sea. As the pressure gauge is lowered, readings of pressure and depth are recorded. Which statement explains how the pressure changes as the gauge is lowered and why this happens?
- AThe density of the sea water decreases so the pressure increases.
- BThe depth of the gauge below the surface of the sea increases so the pressure increases.
- CThe height of the gauge above the sea bed decreases so the pressure decreases.
- DThe temperature of the sea water decreases so the pressure decreases.
