Question

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

Answer 1

I think the answer would be b 

Answer 2

Answer:

The pressure increases with the weight of the water above.

Explanation:

Bathypelagic zone is present above the abyssopelagic zone. The bathypelagic zone extends from 1000 to 4000 m deep in oceans while the abyssopelagic zone extends from 4000 to 6000 m deep in oceans.  

Since the abyssopelagic zone is located deeper than the bathypelagic zone, the weight of water present above it is greater than in the bathypelagic zone.  

The more water present above the abyssopelagic zone exerts more pressure on the abyssopelagic zone. This is why water pressure is greater in the abyssopelagic zone.
