With a very sizable iron core and a (by comparison) wafer-thin crust, I doubt that the earth's crust even approximates a full percentage point.
The earths crust is a part of the outermost layer.
Silicon is a mixture of the minerals of the earths crust. so.... silicon isn't something from the earths crust. -thanks for your question.
The gas which makes up the greatest percentage of earth's atmosphere is nitrogen with 78.08%.
thinner and denser
About 7% of the earths crust
The percentage of Earth's crust is less than one percentage in terms of Earth's volume. The Earth's crust is actually a thin layer.
its the percentage in mass !
6%
Silicon, oxygen and nitrogen
iron and magnesium
5.4%
Oxygen and silicon
Approximately 78%.its percentage is different in different places.it percentage varies from 77.08 TO 79.79

This affirmation is not true; nitrogen exist only in some minerals (see the list below).
