In terms of weight, iron makes up approximately 5% of the earths crust, the fourth most abundant element in the crust. However, remember Earth's Core is nearly all Iron.
SiO2 makes up around 50% of the crust in the form of many types of minerals like jasper, flint, chalcedony, opal, quartz.... There is no one mineral that makes up 99% of the earths crust
it is the lithosphere
Igneous and metamorphic rock make up 95% of the rocks in Earth's crust. Only a thin layer is made up of sedimentary rock.
im pretty sure it earths crust and core or if not the top part of the mantle and the crust above it this is the only infomation i could get sorry
oxygen
Silicon

Nitrogen
the element of find onther place to look it up
