The ocean appears blue primarily due to the absorption and scattering of light. Water absorbs colors in the red part of the light spectrum and reflects and scatters the blue wavelengths, which is why we see the ocean as blue. Additionally, the depth of the water can enhance this effect, as deeper water absorbs more light.<|im_end|>

The ocean appears blue because it contains a lot of salt and is home to many different kinds of fish. The temperature of the water can also affect its color, as warmer water may look different than colder water.<|im_end|>
