Why is The Sky Blue?

Why is the sky blue? Light is a kind of energy that can travel through space. Light from the sun or a light bulb looks white, but it is really a mixture of many colors. The colors in white light are red, orange, yellow, green, blue and violet. You can see these colors when you look at a rainbow in the sky.

The sky is filled with air. Air is a mixture of tiny gas molecules and small bits of solid stuff, like dust.

As sunlight goes through the air, it bumps into the 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.

The intensive process of sedimentation come from Australia Continent, on a very long period produce new island, Papua. A long time ago, Papua was a part of Australia Continent.

The existency of Papua Island, can not be expelled from geological theory, saying that earth, 250 million years ago, only has one continent, Pangea Continent. 240 million years up to 65 million years ago, Pangea Continent divided by two, Laurasia and Eurasia, as the mother of the all continent and mountain now. At that time, Eurasia located on south part of earth, smashed and become Gonwana, and at last become South America, Africa, India, and Australia.

Seeing and watching little thing surround us can give a big thing that you never realize before.But sometimes we get usuall with just a "big stuff". What i mean is our nature, our surroundings, that i would like to call "Languange of Nature". The behaviour of animal, plant, wind, cloud and many other things around us. They won't say "Hey, it's gonna rain" or "Today is a sunny day" or maybe "Watch out, a storm will catch us".No...but these language just leave a sign for us to discover it self, while the sign just left behind if we ignored it, but when human become more sensitive with this untold language, when we discovered what they are trying totell us, then I should welcome you to another amazing world, "The World of Universe, The Language of Nature" that actually already be there, but waiting for us to discover. For example, some trees have leaves that are very sensitive to changes in humidity and will curve upward when it becomes more humid. Increases in humidity are usually associated with rain, so the trees usually curl up their leaves before it rains.
