Of sticking elements together and to simple molecules and then inches of grains of dust and then smashing those grains of toast together into bigger and bigger things which eventually get be rocks and so on that first stage is one of the hardest once you've got something that's sort of mullah you'll sized of a things will start sticking to it and the process guys on the you can create planets silicon is one of the first elements that creates a simple molecule i think it's mainly actually silicon carbide sites it silicon carbon together and they form these simple molecules than other bits and pieces can stick to so in effect silicon plays the key role in building the planet's including the earth atl solsolid planet semaines have the same general kenneth who make up they can pace of minerals made friend the stain elemental building blocks carbon oxygen magnesium and of course silicon the ratio of elements the bill here has led the chemical conditions that had just right for life too much knees em or too little silicon and our planet might have ended up having the wrong balance between minerals to form the types of rocks the makeup on delicious silicon mitch crust the crust that provided a solid framework for our planets and the south the the which water could pool and where the building blocks of life could finally come together silicon is in fact a facilitator for life on earth the elements that again was discovered by swedish chemist in the 1800s yes is the seventh most abundant element in the us and more importantly the second most abundant element in the earth's crust opt oxygen that peers silicon they is very rarely found nature is then even found in a strange volcano russia as pierre crystals the silicon dioxide which is a molecule made up one silicon them attached to two oxygen is actually the most common compound we find and the most abundant one in the ass crust economy takes the form of ordinary sand they you may those that had.
