Introduction_to_oceanography when asked to color the ocean, most of us would choose blue for the ocean. is it true that the ocean is blue? what makes the color of the ocean?

Water absorbs all the longer wavelengths and reflects the shorter blue wavelength.

Explanation:

First let us examine how the human eye perceives color. When we see a red object the object is not inherently red, rather the surface of the object reflects wavelength corresponding to the red color and absorbs the rest of the spectrum.

The ocean consists mainly water. Water has a slight blue tint and not completely colorless. When we see water it is of considerably less volume compared to the ocean. So, when we see water of such a large volume in the ocean the blue tint becomes more apparent. This means that water absorbs all the longer wavelengths and reflects the shorter blue wavelength.

the wrong statement is - c. a desert had more biodiversity than a marsh.

the deserts are one of the places of the planet where there's the least biodiversity. the reasons for that are the climate and the lack of food sources, which hampers both the number of the species that can survive in it, and the number of the individuals in the species itself.

the marshes, on the other hand, are places where there's perfect conditions for lots of organisms to thrive. the temperature is moderate and nice, the amount of water and the food sources are on a high level, so there's an abundance of both plant and animal life in them.
