The plates under the Earth are made of lots of types of rock(sedimentary metamorphic and igneous rock) but underneath is the Earths mantle, a liquid like mix of melted rock.
I am not that old but am taking geography, sorry if this doesn't help but good luck ;)
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.
Crust under the oceans is called oceanic crust.
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.
Continents and oceans are found on Earth's crust, which is the outermost layer of the Earth. The continents are made up of thicker continental crust, while the oceans are located on thinner oceanic crust.

Crust under the oceans is called oceanic crust.
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.
The oceantic crust is (2-4mi)
Earth's crust is far thicker under the continents.
The Earth's crust is thinnest under the oceans and thickest in the mountains.
The Earth's crust is thinnest under the oceans and thickest in the mountains.
The Earth's crust is thinnest under the oceans due to oceanic crust being thinner and denser, while it is thickest through the continents where continental crust is thicker and less dense. The difference in thickness is due to the process of plate tectonics, where oceanic crust is constantly being created at mid-ocean ridges and destroyed at subduction zones.
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.

Oceanic crust, new oceanic crust is produced by seafloor spreading.
