One of the most beautiful element of nature is the sky. The sky plays an important role in the beauty of nature especially because of its blue colour and how the blue colour contrast against the green trees and the bright sun. 

Now have you ever wondered why the sky is blue? , I bet you thought it's because of the reflection of the ocean or the colour of the sea well if that's what you thought them I'm sorry to tell you that you had the wrong impression all this while. Why is the sky blue? I ask again, there are different colours in the spectrum of light and blue happens to be one of the colours , but the big question if why is blue seen . The white light coming from the Sun is really made up of all the colors of the rainbow. We see all those colors when we look at rainbows. Raindrops act as tiny prisms when lit by the Sun, bending light and separating it into its different colors.Blue light is scattered more than other colours because it travels as shorter and smaller waves this is why we see a blue sky most of the time.

Sunlight reaches the earth and is scattered in all directions by gases and particles in the air. Blue light is scattered more than other colours because it travels at shorter and smaller waves. 

One of the first questions a curious child often asks about the natural world is “why is the sky blue?” Yet despite how widespread this question is, there are many misconceptions and incorrect answers bandied about  because it reflects the ocean; because oxygen is a blue-colored gas; because sunlight has a blue tint  while the right answer is often thoroughly overlooked. In truth, the reason the sky is blue is because of three simple factors put together: that sunlight is made out of light of many different wavelengths, that Earth’s atmosphere is made out of molecules that scatter different-wavelength light by different amounts, and the sensitivity of our eyes. Put these three things together, and a blue sky is inevitable. Here’s how it all comes together.

Clouds, on the other hand, are made of water droplets that are much larger than the wavelengths of visible light. The way they scatter sunlight is determined by how the light is refracted and internally reflected by, and diffracted around, the cloud droplets. For these particles the difference between the scattering of blue and red light is not nearly so large as it is for gas molecules. Hence, our eyes receive substantial scattered light at all visible wavelengths, causing clouds to appear more white than blue, especially when viewed against a blue sky background. The next question on your mind will be so what happens to all the “non-blue” wavelengths? They are still mixed together, unscattered by the atmosphere, so they still appear white. The scattered violet and blue light dominates the sky, making it appear blue. What happens to the violet? Some of the violet light is absorbed by the upper atmosphere. Also, our eyes are not as sensitive to violet as they are to blue.

So you see that's why the sky is blue.

If we are going to talk about material things and needs, then money is important, but if we are going to talk about one’s happiness, then money is not that important. From your list of reasons of why money is important, it all seems to point to material things and needs, except for the second to the last one in which you need money to give to charity. What if money wasn’t invented

If money wasn’t invented, I’d believe the same problems would exist. Money is only a vehicle. Human nature dictates how it is used and perceived.

 We should not overvalue it because then greed can consume you. We should also not undervalue it either because it is needed for survival.

Money is extremely important. People who says money is not important had never been poor. Once the basic are taken care of, money is still important but I agree there are more important things like heath, family, and much more.

Money is important – I agree 100% – for all of the reasons mentioned and more. For me I think the danger is becoming obsessed with MORE money. How much do you really need to live comfortably or even beyond comfortable? Yet so many people just keep working and slaving to have MORE money. And the cost is significant – missed time with family, spouses, and downtime for yourself. Nothing wrong with money but as the saying goes, the LOVE of money is the root of all evil. We should use money not be used by our desires to always have more.
