Best answer out of 2 people get !
explain how temperature and pressure vary at different depths in the ocean.

The deeper the depth, the lower the temperature, and the higher the pressure.

At sea level,the pressure of the atmosphere pushing down on the ocean surface is referred to as 1 atmosphere of pressure.An atmosphere is the pressure exerted on a surface at sea level by the column of air above it.As you go below the ocean's surface ,the pressure increases because of the force of the water molecules are pushing down.

Ithink it’s b but not 100% sure
