Oceanic crust, new oceanic crust is produced by seafloor spreading.
The crust is the outer or surface layer of the planet.
mantle
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.

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.
The oceantic crust is (2-4mi)
The layer that is thinnest under the oceans is the crust. While it is thinnest in those underwater regions, it is the thickest in the regions where mountains are.
Earth's crust is far thicker under the continents.
The crust is typically thicker under the continental shelf compared to under the oceans. This is because the continental crust is made of lighter granite rocks which are less dense than the basaltic rocks of the oceanic crust, resulting in thicker continental crust.
Gulfs are found around the edges of oceans. They are usually formed by movements of tectonic plates under Earth's crust.
The Earth's crust is thinnest under the oceans and thickest in the mountains.
