Detailed explanation-3: -Oceans are made of five layers or depths. Each layer has different characteristics, such as the temperature and the amount of light. They have unique creatures living within them. There is plenty of sunlight and heat in this zone although both decrease as you go deeper.

Detailed explanation-4: -4. The Abyss Zone. As you might guess from the name, the ocean is pretty unforgiving in this layer. It’s still completely dark and frigid, and contains most of the ocean floor (except for where it dips down into trenches).
