12.Transition zone: Part of the ocean that extends from the surface zone to about 1 kilometer. The temperature rapidly drops.

13. The deep zone has very little light.

14. Deep zone: Part of the ocean that extends from the bottom of the transition zone about 1 kilometer to the ocean floor. Coldest part of the ocean.

15. There are many ocean zones, the neritic zone is one of them.
