Why is the sea and sky blue?
The sky is blue due to a phenomenon called Raleigh scattering
. … The ocean is not blue because it reflects the sky, though I believed that up until a few years ago. Water actually appears blue due to its absorption of red light. When light hits water, the water’s molecules absorb some of the photons from the light.
What Colour is the ocean?
The ocean is
blue
because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.

Why is the sea salty?

mainly caused by rain washing mineral ions from the land into water
. Carbon dioxide in the air dissolves into rainwater, making it slightly acidic. When rain falls, it weathers rocks, releasing mineral salts that separate into ions.
