How does pressure change with increasing depth underwater?

As divers descend underwater, they experience an increase in pressure that is directly related to the depth. Specifically, for every 10 meters (or approximately 33 feet) of sea water, the pressure increases by about 1 atmosphere. This phenomenon occurs because the weight of the water column above the diver exerts force on the body, leading to an increase in pressure with depth.

At sea level, atmospheric pressure is approximately 1 atmosphere. As a diver goes deeper, they not only experience this atmospheric pressure but also the additional pressure from the water above them. Therefore, at 10 meters, the total pressure would be around 2 atmospheres, at 20 meters it would be roughly 3 atmospheres, and so on. This understanding is crucial for divers as it relates to concepts like buoyancy, decompression, and environmental physiology during dives.

The other options do not reflect the measurable relationship between depth and pressure change in water.
