From lithospheric interactions with the asthenosphere.
The silica content of Earth's crust under the oceans is around 50-60%. Silicon is one of the most abundant elements in the Earth's crust, with silica being a major component of minerals like quartz and feldspar found in oceanic crust.
Silicon is typically extracted from silica, which is found in the Earth's crust as quartz. The most common method to extract silicon involves heating silica with carbon in an electric arc furnace to produce silicon and carbon monoxide gas. This process is known as the carbothermic reduction of silica.
A divergent plate boundary would have less silica content compared to a convergent plate boundary. Divergent boundaries involve the separation of tectonic plates, with new oceanic crust forming from magma that is relatively low in silica content. In contrast, convergent boundaries involve the collision of tectonic plates, resulting in the melting of crust with higher silica content, leading to more explosive volcanic activity.
Silicon is one of the most abundant elements in the crust and mantle. Since all magmas are derived from the crust or mantle, the silica content will be significant, and dependent on its source for its constituent percentage.
The crust is the outer or surface layer of the planet.
The silica content of the Earth's crust beneath the oceans is typically lower compared to the crust beneath continents. This lower silica content results in a type of magma known as basalt, which is commonly associated with oceanic volcanoes like those found along mid-ocean ridges.

oceanic crust is made of basalt while continental crust is made of silica rich rocks like granite.
earths crust includes ocean floors and
almost no silica in ocean water but most of its the earths crust.
it has been washed into the oceans as the continental crust has eroded.
Oceanic crust, new oceanic crust is produced by seafloor spreading.

Earths crust extend deeper below the continents than below the oceans basins (or at least this is what I think).
