" The sky appears blue" because and more misconceptions..

There are many misconceptions astronomical science and more out there that people either believe until they actual reasons etc are know or understood. Part education, part thinking , part reasoning and more.

The sky appears blue because while sunlight contains blue that is bounced around by air molecules .
The Oceans are blue, it is not the reflection of the sky, because water absorbs sunlight's red wavelength which leaves more of the blue to reflect off the sea.

Meanwhile the atmosphere on Mars is pinkish colored. Why? Because the soil and rocks on Mars are red and the resulting dust is lofted into the thin air of the planet.
