What are the photic and aphotic zones of the ocean?
The photic zone is the top 200 meters of water. The aphotic zone is water deeper than 200 meters. The deeper you go, the darker the water gets. That’s because sunlight cannot penetrate very far under water.
What ocean zones are Aphotic?
The division labeled ‘aphotic zone’ contains this additional text: “The aphotic zone incudes: The bathypelagic (midnight) zone between 1,000-4,000 meters; the abyssopelagic (abyss) zone between 4,000-6,000 meters; and the hadopelagic (hadal) zone is 6,000 meters and deeper.
Which are the only two photic zones in the ocean?

What are the three photic zones?
The ocean is generally divided into three zones which are named based on the amount of sunlight they receive: the euphotic, dysphotic, and aphotic zones.
- Euphotic Zone (Sunlight Zone or Epipelagic Zone)
- Dysphotic Zone (Twilight Zone or Mesopelagic Zone)
- Aphotic Zone (Bathypelagic, Abyssopelagic, and Hadopelagic Zones)
What are the 5 zones of the ocean?
