According to the NYS Earth Science Reference Table, most of the Earth's crust is made up of 46.4% oxygen, and 28.15% silicon (silicon-oxygen tetrahedron) by mass. But by volume, it is made up of 94.04% oxygen, and 0.88% silicon.
Lithospheric plates.
There is no specific term "tectonic plantes". It seems like a misunderstanding. Tectonic plates are large sections of the Earth's outer shell that move around on the semi-fluid asthenosphere beneath them, resulting in phenomena like earthquakes and volcanic eruptions.
The Earth's surface is broken into large pieces called tectonic plates. These plates float on the semi-fluid asthenosphere layer beneath them and interact at plate boundaries, where geological phenomena such as earthquakes and volcanic eruptions occur.
The mantle is inferred to have convection currents that cause tectonic plates to move. Heat from within the Earth creates these currents, leading to the movement of the rigid plates on the Earth's surface.
As Earth's mantle drags on the bottom of tectonic plates, it creates stress and friction that can cause the plates to move. This movement can result in various tectonic activities such as earthquakes, volcanic eruptions, and the formation of mountain ranges as the plates interact with each other.
No the tectonic plates are on top of the crust.
