Question

Why is pressure greater in the abyssopelagic zone than in the bathypelagic zone?

Answer 1

The pressure increases with the weight of the water above.

Answer 2

Answer:

Abyssopelagic zone lies just below the bathypelagic zone and the pressure in the abyssopelagic zone is the much more than the layer above it. The hydrosatic pressure there is much more because of the depth. The pressure increases by one atmosphere with each 10 meter increase in depth and the abyssal pressure ranges between 200 and 600 atmosphere. Thus, the pressure in the abyssopelagic zone is more than in the bathypelagic zone.
