The Layers of the Ocean

Understanding the Layers of the Ocean

In this section, we will learn about the structure of the Earth and oceanic crust. We will also explore the different layers of the ocean and their corresponding depths.

The Continental Shelf and Slope

  • The continental shelf is a ramp of continental crust beneath the ocean that extends off the coast.
  • The continental slope drops off quickly into a steep incline.
  • The photic or epipelagic zone is between 0 and 200 meters deep, where there is enough light present for photosynthesis to take place.
  • The mesopelagic zone extends from 200 to 1000 meters, where sunlight can no longer reach.

The Bathypelagic Zone

  • Temperatures in the abyssopelagic zone stay at a chilly 4 degrees Celsius, and pressures reach 200 to 600 times atmospheric pressure at sea level.
  • The hadopelagic zone extends from 4000 to 6000 meters and is only found in deep ocean trenches.

Conclusion

  • It's important to have a basic understanding of the layers of the ocean and their corresponding depths.
Video description

We've gone over the structure of the earth, including continental and oceanic crust, but there is a vast ocean that sits atop that oceanic crust. If we want to understand every area of Earth's surface, we will certainly will have to discuss the layers of the ocean. How far down can light reach? What happens to the temperature and pressure as we venture down? What kinds of organisms might we find? Let's dive in and find out!
