About 95%.
Oxygen and silicon
Igneous and metamorphic rock make up 95% of the rocks in Earth's crust. Only a thin layer is made up of sedimentary rock.
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.
it is the lithosphere
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

Just to say: This question refers to rock groups. Not what type of rock.Igneous rocks make up most of the earth's crust.
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.

The principle element found at the Earth's core is iron.

it is the lithosphere
Igneous rock comprises the majority of Earth's crust.
It makes up 99.99% of earths crust so it's not that abundant
