Silica is most commonly found in nature as sand or quartz. As to stone age people, they are all dead. They only lived in the stone age. If you think you are one, then you need to seek professional help.
They were farmers. And hunters and gathers
Most people prefer their steel not to have glass in it.
The people who came in this world 1st realized that the world is full of music, and the first people who came was the Stonage people.
How many people work in the silicon valley
Silicon is a element.! this is because anything from the periodic table is in fact elements! :)
Silicon Valley was the area of California in which the Computer Age began in America. It is the place where the majority of the US computer chips are designed and manufactured. The name Silicon comes from the element, which is used in computer chips as a semi-conductor. This means that it only lets current through in a single direction - key for nearly all circuitry in modern life.
Impossible to say.
Some people do believe that life can be silicon based but so far its just a theory with no definite answer.
To start off, Silicon and oxygen are among the most abundant elements in the universe: oxygen is the third most common element and silicon is the seventh. They readily combine to form silicon dioxide (silica), making it one of the most common solid materials in the universe. Additionally, silica is less dense than many other abundant substances within Earth. Therefore when Earth formed, the more silica-rich materials tended to float toward the surface.
Silicon exists in sand and in glass. And since the development of electronic circuits, people have learned that silicon is also a semiconductor suitable for use in transistors that are used in many electronics today.
animals and people breath out carbon dioxide and plants use carbon dioxide
Talk to whomever asked this question. Let them know that there is more than one element that does this.What most people think when they think of chains of atoms is carbon. But silicon also forms long chain molecules. This is not an obscure fact; it's very well known and the basis of products all around you, like hair conditioners and bathtub caulk.
