Answer:
The pressure increases linearly with the depth below the surface
Step-by-step explanation:
The pressure at the bottom of a column of fluid is given by:

where
is the atmospheric pressure
is the fluid's density
g is the gravitational acceleration
h is the depth below the surface of the fluid
As we see from the equation, the pressure is directly proportional to h, the depth below the fluid surface: therefore, as h increases, the pressure increases as well.
