Oceans are located all over the world. The oceans are the Atlantic Ocean, the Pacific Ocean, the Arctic Ocean, and the Indian Ocean. All of the oceans cover 70% of the Earth.
      The ocean is also very salty. In every gallon of ocean water there is at least one cup of salt.
      Do you know how many zones are in the ocean? There are three. The top is the euphotic, which is where the light can penetrate. The next zone is the disphotic, which is where the light looks as if it would be twilight on land. The deepest zone is the aphotic, which is where it is extremely cold, dark, and low in nutrition.
