By mass, the Earth is composed of mostly iron (35 percent), oxygen (30 percent), silicon (15 percent), and magnesium (13 percent). The Earth's Surface is predominantly water!

The surface area of the earth is predominantly water (about 70%), and I sincerely hope this isn't a serious question...

The average depth of the oceans is only about 3000 meters (0,05 % of the radius of the Earth) so most of the mass of the earth is not water.

To shorten this down....the earth is mostly water.
