When you look up and see the bright blue sky... what do you feel? How can its radiance affect your mood or emotion? Can it lighten up your heavy heart or deepen a wound that is pained by life's misfortunes?
By just gazing upon its beauty with different cloud formations and shapes... we can build a promising future. Our imagination will take us somewhere beneath the vast view of this nature's wonder.
Well, to those who still wonder how these clouds are formed... here's an illustration to explain these amazing white luminous beds of cotton floating in the sky.
When the sun's heat absorbs by Earth's atmosphere, the warm air rises, expands and eventually cools. The cooling air becomes lighter and less dense than the surrounding air. When the moisture is enough to condense out of the air parcel, then clouds are formed.
Why is the sky color blue?
Light coming from the sun is actually a mixture of different colors and because the sky is filled with air and dust particles, sunlight pass through the air. It bumps into the gas molecules and dust. When light hits a gas molecule, it may bounce off in a different direction. Some colors of light, like red and orange, pass straight through the air. But most of the blue light bounces off in all directions. In this way, the blue light gets scattered all around the sky.
When you look up, some of this blue light reaches your eyes from all over the sky. Since you see blue light from everywhere overhead, the sky looks blue. (Source)
