What are the major characteristics of the deep zone of the ocean?
Very very cold.
The deep zone is an area of very cold water that extends from the bottom of the thermocline to depths of 4000 meters or more. Within the deep zone, the temperature decreases slightly. Th depth of more than 1500 meters, the temperature is about 4 degree celsius. So its temperature is above freezing .
Remember, this cannot be found in the polar regions
