What else can I help you with?
Is the underlying rock beneath the ocean floor silica?
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.
What is the name of the rock beneath the ocean called?
the rock beneath the ocean is basalt
What is name of rock beneath the ocean?
coral
What extrusive igneous rock is found on ocean floors?
Basalt
What is the rock beneath the ocean called?
cream cheese
What plutonic igneous rock forms beneath mid-ocean ridges?
The plutonic igneous rock that forms beneath mid-ocean ridges is primarily gabbro. Gabbro is a coarse-grained rock that crystallizes from magma that cools slowly beneath the Earth's surface, typically associated with the upwelling of magma at mid-ocean ridges. This process contributes to the formation of new oceanic crust as tectonic plates diverge.
What two layers of Earth are made of rock?
The two layers of Earth that are made of rock are the crust and the mantle. The crust is the outermost layer, consisting of solid rock that forms the continents and ocean floors. Beneath the crust, the mantle is composed of semi-solid rock that flows slowly over geological time. Together, these layers play a crucial role in tectonic activity and the Earth's geology.
At locations where sea floors spreading occurs rock is moved away from a mid-ocean ridge what replaces the rock as it moves away?
continental crust.
What is the crust beneath the ocean called?
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.
Where is most of the phosphorus stored in the biosphere?
Phosphorus is trapped in phosphate that makes up phodphate rock and the sediments of ocean floors.

Which soil layer is least similar to underlying rock?
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.
