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.
crust
Another word for Earth's outer surface is "crust."
Carbon makes up approximately 0.03% of Earth's atmosphere and is the fourth most abundant element by mass in the planet's crust.
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%
iron and magnesium
Less than 1%.
5.4%

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.
Hydrogen I believe
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.
