Silicates are the mineral group that make up the highest percentage of Earth's crust, accounting for about 90% of the crust by volume. They are composed of silicon and oxygen, the two most abundant elements in the Earth's crust.
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.

Carbon makes up approximately 0.03% of Earth's atmosphere and is the fourth most abundant element by mass in the planet's crust.
Oxygen is the most abundant element in the Earth's crust, atmosphere, and oceans. It makes up about 46% of the Earth's crust by weight, about 21% of the atmosphere, and is a key component of water in the oceans.
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 !

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.

Silicates are the mineral group that make up the highest percentage of Earth's crust, accounting for about 90% of the crust by volume. They are composed of silicon and oxygen, the two most abundant elements in the Earth's crust.
The Earths crust is approximately 650 km deep.
