Near shore, sedimentary. Deep ocean, extrusive igneous, mainly basalt.
The underlying rock beneath the ocean floor is primarily basalt, which is a mafic rock rich in iron and magnesium. Silica-rich rocks like granite are typically found in continental crust, not beneath the ocean floor.

continental crust.
The crust beneath the ocean is called oceanic crust. It is thinner and younger than continental crust, primarily composed of basaltic rock formed at mid-ocean ridges through volcanic activity.
Phosphorus is trapped in phosphate that makes up phodphate rock and the sediments of ocean floors.

The topsoil layer is typically least similar to the underlying rock, as it is a combination of organic matter, minerals, and microorganisms that have been weathered and broken down over time. This layer tends to have a different composition and structure compared to the solid rock beneath it.
The dominant rock type in ocean crust is basalt, which forms from solidified lava. In continental crust, the dominant rock type is granite, which forms from the cooling and solidification of magma beneath the Earth's surface.
