the sky is not blue coz of the reflection of the ocean

Hello, I will be arguing that the region of the atmosphere seen from the earth is a blue color.

Evidence this is true:

Pacific ocean and sky

This is a picture taken over the pacific ocean.
You can clearly see over and above the horizon an atomosphere which is commonly know as the "sky".
In this photo, the sky is clearly blue in color. So, this should be evidence enough that the sky is blue regardless of the reflection of the ocean. You can actually look in the reflection in the ocean, and it actually reflects a blue sky unless it is very murky. Certain types of plankton and fishes "bioluminescence" are also responsible for the blue color of the ocean at times, but that is another topic on various colors of the ocean.

The sky is made up of a variety of gaseous molecules and matter. It has a high content of oxygen, water, along with nitrogen, argon, and carbon dioxide. But the sky also has other particles. The general composition of the sky also depends on place, weather, time of day, and many other factors. Mars for example, has a pinkish sky because of the high content of iron particles in its thin atmosphere. A volcanic explosion, excessive dust, pollution, and fog are things that can change the composition of the sky or how the sky appears.

The sky also changes its density depending on where you are in the sky. As an example, the sky is denser near the earths troposphere than it is in the vicinity of the exosphere.

The reason our sky is blue is because rayleigh scattering. When the sunlight strikes air molecules, other particulates, water, and iceform clouds they are scattered in all different directions. Because blue light travels in shorter and smaller wave lengths than other light, the result is a blue sky. Obviously at night, when there is no sunlight, the sky is dark. To elaborate on the reason a sunset is red, is because the sunlight is traveling through more of the sky to reach our eyes. The red light is unscattered at that time of day because their long wavelengths. And clouds are white in color because the water droplets scatter all wavelengths of the spectrum equally. Similar to how lipids are responsible to much of the scattering within milk, giving it its white color.

Take a look at the wavelengths of blue light:

I'm suprised my opponent made the debate 1 round, yet offered so little.

To anyone concerned: The sky is actually purple, we just see the sky as blue because it is the nearest color that we can see on the visible light spectrum. We are unable to see purple on the visible light spectrum, as such we see blue.

correction: where there is more atmosphere to adsorb the higher spectrum due to the position of the earth

the sky is not a mirror, it merely blocks long waved spectrum's until dawn or dusk, where it absorbs the higher spectrum.

the sky is a mirror it just reflects the water
