Answer:
Water is not blue but it appears blue when sun light falls on it. Red, yellow and orange colors of sunlight are strongly absorbed by water , being of longer wave length where as blue because of its shorter wave length is returned back. Thus water appears blue .
Darker sand comes from a number of minerals that are often denser and heavier than tan and quartz. A common mineral giving the beach a dark color is Magnetite. You may also be familiar with black-sanded beaches derived from volcanic sediments such as the beach seen in the cover image.
