abyssal zone
The temperature layers in ocean water are typically divided into three main zones: the surface zone, the thermocline, and the deep zone. The surface zone is the warmest and most variable in temperature due to interaction with the atmosphere. Below the surface zone is the thermocline, where temperature decreases rapidly with depth. Finally, the deep zone is characterized by consistently cold temperatures.

The ocean zone characterized by high water pressure, low temperatures, and no sunlight is the hadal zone. This zone extends from depths of 19,685 to 36,100 feet (6,000 to 11,000 meters) and is found in deep ocean trenches. Organisms living in this zone must adapt to extreme conditions, such as lack of sunlight and high pressure.
The climate in the Neritic Ocean zone is generally calm with mild temperatures. This is the area within the ocean that the sunlight can reach to the bottom of the water. This zone offers favorable conditions for many marine animals.
A rapid change in temperature with depth in the ocean is called thermocline. A rapid change in density with depth in the ocean is called the pynocline.Thermocline
The hadal zone, found in the deep trenches of the ocean floor, is considered the darkest ocean zone. This zone can reach depths of over 6 miles (10 kilometers) and is characterized by extreme pressure, cold temperatures, and a lack of sunlight.
