Silicate minerals such as quartz and feldspar are the most common minerals located in earths crust
Silicon is a mixture of the minerals of the earths crust. so.... silicon isn't something from the earths crust. -thanks for your question.
crust
because of the metamorphism when temperature and pressure inside earths crust change that were present in the rock when it formed
Fossils, although technically they are not preserved in the earths crust; the minerals in the bones and pore spaces have been replaced by other harder minerals which take much longer to weather.There are a number of different fossilization processes. See this link :How are Fossils Formed?
The Earth's Lithosphere is the Crust and Upper Mantle. Fossil Fuels or Minerals Fuels are fossle source fuels, that is, carbon or hydrocarbons that are found on the earth's crust
Quartz and feldspars are the most common silicate minerals of the crust.
Crust
A rock takes millions of years to form. It is formed underneath the earths crust, where there is immense pressure and heat that compacts minerals to form rocks.
