When studying the ocean floor, what three zones do oceanographers divide the ocean floor into?

There are five ocean layers usually called zones. The name of the ocean zones is defined from the ocean surface. The first zone is the epipelagic zone, the second is the mesopelagic zone, the third is the bathypelagic zone, the fourth is the abyssopelagic zone and the last one is the hadalpelagic zone. The water depth also gets influence by pressure. The deeper you swim into the ocean, the greater water pressure pushes down on you. Therefore, we should discuss one by one the ocean layers for a better understanding of ocean nature.

Explanation: Oceanographers divide the ocean into layers like a cake. It has significant meaning because the ocean has different water densities. It means that water weight per unit volume has a difference of spaces. It's between water molecules and the water density is different from one layer to another in the ocean. Then, It increases along with the increasing depth of the ocean. The density of ocean water gets influence by its temperature. The relationship between density and temperature is relatively inverse. Then, also occurs the inverse. The water density has its maximum, vat the temperature of 4 degrees Celsius for pure water.

answer; i believe the correct answer is (clockwise and outward) about the center;
