No. The crust is the least dense of Earth's layers. The inner core is the densest player.
The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.
If you talk about elements, then oxygen is O, and O is found in many, many COMPOUNDS. So, if a compound is found in the crust, and if it contains oxygen (like water, H2O), then the element oxygen will be counted. It doesn't have to be in a gaseous form. In addition, O2 gas can also be found dissolved in some liquids.
The Earths crust is approximately 650 km deep.
Very probable these compounds are water and silicon dioxide (in the Earth crust).
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.

The earth's crust is not stress
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.
