Why can't it be purplish?
Or greenish? Or slightly silver-ishhhh?
Actually, why is it blue?
Is the sea's reflection hitting the sun's rays or something?
I need to know!
You guys are bigger, better, and smarter.
Don't you know?
Maybe I'll be a scientist one day..
I said maybe, so don't get your hopes up.

reflection of the sea..so ive heard..not a big scientist here :P
u can always google ;)
"On a clear sunny day, the sky above us looks bright blue. In the evening, the sunset puts on a brilliant show of reds, pinks and oranges. Why is the sky blue? What makes the sunset red?
To answer these questions, we must learn about light, and the Earth's atmosphere. "
the answers you can find here: http://www.sciencemadesimple.com/sky_blue.html
the sea actually reflects the colour of the sky
i like the sky as it is, its perfect!
sometimes it gets golden, and gray and purple too
specially during the rainy days!
observe a lil more xeeko!
hehe.. I donno.. A friend of mine said dat the sea is blue cos it gets the reflction from the sky.. And the sky isnt always blue.. Sometime its orange, and sometimes grey.. and yet, mostly blue.. =)
shweeetikle, i can always google, but not everything there makes sense... xD
t, urmmm.... okay... thanks
.mini, well it is all those colours and more, but its mostly blue. and if the sky is those colours, why is the sea still blue? aaaah, my head hurts...
shaha, refer to mini's reply :]
yeah why shud it be blue it can be green or red or pink always blue dho.. and the sea hmm it shud be yellow and xyko becom a scientist and find all these probs u will be famouse i hope..........
cute risa, i do not plan on being a scientist, I WANNA BE A GRAPHIC DESIGNER!!!! lol, thanks
i havent gone much into the details of it but as far as i know its to do with the refraction of light as it passes thru the atmosphere/ozone/whatever. thats why we see a reddish colour during dawn and at sunset as the angle of refraction changes since the sun is so close to the horizon. at that angle when light is refracted the colour red is whats projected onto the sky whereas during daytime its the colour blue. hope that answered your Q. And i dont think you need to be a scientist for this.
ahhhhhh, i get it. i think.... =S
keke sorry ohh well anyway its ur choice not mine i am not ur mother to tell u everything lol
It works kind of like this. From the colour spectrum red has the longest wavelength and blue the shortest. When light enters the atmosphere (and even the sea water) it 'bends' (refracts) as it is always entering a denser medium than it was initially in. Blue refracts the most and actually slows down the most as it covers the least distance in any given time due to its short wavelength. So even when the other colour wavelengths have passed, blue is usually still present and this makes the sky 'blue'. If you go around 5 meters or something underwater you won't be seeing red. Another few and no green. Then you'll only be seeing all blue upto about 50 meters in depth and beyond that nothing. Unless you have another light source like a torch with you. Btw the numbers might not be exact but that's what I can remember now. And sorry for being so technical. One day if you decided to go in the science field you would understand. Hope this helped
