  2. Epipelagic Zone (The Sunlight Zone) • 0-600 feet • Very warm water because that is where the sun hits the surface • Allows enough sunlight for photosynthesis to occur. Includes a wide variety of ocean plants. • Most marine that lives in the ocean live in this layer.

  3. Continental Shelf • A submerged border of a continent • Has a gradual slope. Depths up to 200 meters. • It extends to a deeper part of the ocean, going into another layer.

  4. Mesopelagic Zone (The Twilight Zone) • 600-3,300 feet • Not as much light is let through as the sunlight zone, temperatures of 40 degrees. • most organisms migrate to the surface to feed at night or live off the falling debris from the Epipelagic ecosystem. • bioluminescent creatures that use chemicals in their bodies to produce light.

  5. Bathypelagic Zone (The Midnight Zone) • 3281-13, 124 feet • Cold temperatures due to lack of light. Around 4 degrees Celsius. • No light penetration what so ever. Only light that can be found is the light produced by creatures such as angler fish. • Even though there is barely any light, there are large amount of creatures found in this zone.

  6. Continental Slope • The region between a continental shelf and a continental rise • Usually 12.4 miles wide. Descends into other zones all the way to the ocean floor. • Consists of mud and silt (a cross between sand and clay)

  7. Abyssopelagic Zone (The Abyss) • 3, 281-13, 124-feet • Abyssopelagic translates to “no bottom”. • Water temperature is near freezing. • Very few creatures are found in this layer. Any that exist are invertebratessuch as basket stars and tiny squids • The ocean floor makes up ¾ of this layer.

  8. Continental Rise • A wide gentle incline from the ocean bottom to a continental slope. • Made up of mostly mud, silt, and sand. • Can be hundreds of miles wide and has a smooth surface.

  9. Ocean Basin • Large geological basins placed below sea water. • Can be active and change size, can be inactive and remain as is. • They change size depending on if they are located on a moving plate.

  10. Hadalpelagic Zone (The Trenches) • 19, 686-to the bottom deepest parts of the ocean that are immeasurable. • Mostly found in deep trenches or canyons. • Temperature is just above freezing and pressure is overwhelming. • Small, and not many, invertebrates can be found here.
