Basic Earth And Environmental Science

 The Earth has not always been this way. It has taken a great length of time to produce the features that we now observe. In the distant future the Earth will appear different again because changes are continuously taking place. Scientists agree that the Earth formed from a large cloud of gas and dust. As the gases and dust cooled, the Earth developed, slowly forming a ball-shape with a solid surface. This surface is called the crust.

The solid materials of the crust are called ROCKS. The first rocks resulted from the cooling of molten material. These rocks are called ingenous rocks. Granite is one.

Here is a picture of Granite:

Sharks, the most feared animals?

The truth is, that sharks are not agressive and that they attack humans mostly by mistake as to thinking they're seals or something that they normally eat. Sharks most of the times just take a bite and they'll leave you alone when realising that you're not something that they usually eat. The mistakes that they do is mostly due to poor eyesight. Then again, sharks make up the poor eyesight with an incredible sense of smell.

Theory on why the sky is Blue

Well, I have a theory which could result as an answer to as why the sky is Blue. What I think is that the sky is Blue because the Earths water, reflects of the light given by the sun, which would also explain why the sky is Black at night since there is no sun. There is an experiment that you can try to prove this too. If you put a brightly colored tooth brush or some other brightly colored object into a cup which in the inside is White, and    pour some water in, the water will turn what ever the color of the object that you put in. It has the same principle as to why the sky is Blue but only on a smaller scale.

If you have your own theories on why the sky is Blue, feel free to post it in the comments.
