The percentage of carbon dioxide is in the earth's crust is only 0.005%. Oxygen on the other hand makes up for 47% of the crust of the earth.
iron and magnesium
Silicon is the element in the Earth's crust that has 14 protons. Quartz is crystallized Silicon Dioxide. Flint is also silicon dioxide. The compounds of Silicon are known as silicates.
half of earths layer
Earths under crust surrounded by Upper Mantle (35-60 km) .The mantle is composed of sillicate rocks that are rich in iron and magnesium relative to the overlying crust.
it gets soggy
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
About 0.02 -0.03 %.

5.4%
Oxygen and silicon
Earth's crust would be silica. Living things would be carbon.
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.
