The earth's crust has about 47% oxygen and about 28 % silicon in it by mass (rounded off). There is a bit of variability of the figures, depending on whose study you use to collect the data. Click on the link below to compare a few studies, to check facts and to learn more. Just reading down the table makes it worth the few moments it takes to surf on over.
