What are the major ocean zones?

The ocean is divided into five zones: the epipelagic zone , or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the ...

What are the three main zone of the open ocean?

• Epipelagic zone (ocean surface to 200 meters deep). ...
• Mesopelagic zone (200-1,000m) – This is also known as the twilight zone, because light becomes limited. ...
• Bathypelagic zone (1,000-4,000m) – This is a dark zone where water pressure is high and the water is cold (around 35-39 degrees).

• Zone 5 – Hadalpelagic.

What is in deep sea?

This is the deep sea. Most are familiar with the surface layer, which extends down 650 feet (200 m) and receives the most sunlight, allowing photosynthetic organisms like phytoplankton to convert sunlight to energy. It is the home of pods of dolphins, schools of fish, and shoals of sharks .

Where are open oceans located?

The open oceans or pelagic ecosystems are the areas away from the coastal boundaries and above the seabed . It encompasses the entire water column and lies beyond the edge of the continental shelf. It extends from the tropics to the polar regions and from the sea surface to the abyssal depths.

At what depth is there no light in the ocean?

Light may be detected as far as 1,000 meters down in the ocean, but there is rarely any significant light beyond 200 meters . The ocean is divided into three zones based on depth and light level. Although some sea creatures depend on light to live, others can do without it.

What ocean zone do sharks live in?

Habitat. Deep sea sharks live below the photic zone of the ocean , primarily in an area known as the twilight zone between 200 and 1,000 meters deep, where light is too weak for photosynthesis. This extreme environment is limited in both sunlight and food.

How deep is the abyssal zone?

The Abyssopelagic Zone (or abyssal zone) extends from 13,100 feet (4,000 meters) to 19,700 feet (6,000 meters) . It is the pitch-black bottom layer of the ocean.

Is there a bottom to the ocean?
