Portion of the earth's crust that lies beneath the ocean floor?
The portion of Earth's crust that lies beneath the ocean floor is called oceanic crust. It is thinner and denser than continental crust, primarily composed of basaltic rocks, and formed at mid-ocean ridges through volcanic activity.
What crust makes up the ocean floor?
The ocean floor is mainly composed of basaltic crust known as oceanic crust. This crust is thinner and denser than continental crust and is formed through volcanic activity at mid-ocean ridges.
The youngest rocks on the ocean floor are located?
The youngest rocks on the ocean floor are located at mid-ocean ridges, where new oceanic crust is formed through volcanic activity. As the crust spreads away from the ridge, it gets progressively older. This process is known as seafloor spreading.
What are 2 types of crust?
The two types of crust are oceanic crust, which is denser and thinner, and continental crust, which is less dense and thicker. Oceanic crust is typically found beneath the ocean floor, while continental crust makes up the landmasses on Earth.
Crust under the ocean is called?
Crust under the oceans is called oceanic crust.

What crust makes up the ocean floor?
The ocean floor is mainly composed of basaltic crust known as oceanic crust. This crust is thinner and denser than continental crust and is formed through volcanic activity at mid-ocean ridges.
Why the crust is thinner than the ocean floor?
The Earth's crust is thinner than the ocean floor because the oceanic crust is formed at mid-ocean ridges where heat from the mantle creates new crust through volcanic activity. This process creates younger, hotter, and thinner crust in the ocean compared to the older and thicker continental crust.
What is the type of crust formed on the ocean floor?
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
Is there magnetic strips on the ocean floor are places where oceanic crust sink back to the mantle?
Is there magnetic stripe son the ocean floor are places where oceanic crust sink back to the mantle
What ocean-floor feature is associated with areas where oceanic crust is broken down?
The mid ocean ridge is the area of the ocean floor that is associated with the breaking down of the oceanic crust. This area is known for seafloor spreading.
What is oceanic crust composed of?
The oceanic crust composed of sima, mafic rocks and basalt. This is the top layer of the lithosphere which is found in the ocean floor.
Where are the elder parts of the ocean floor located?
Oceanic crust is created at mid-ocean ridges and (through the creation of new oceanic crust) is pushed toward a convergent plate boundary where it is subducted. So the oldest oceanic crust would be located at a convergent plate boundary where the oceanic crust is being subducted under continental crust.
The youngest rocks on the ocean floor are located?
The youngest rocks on the ocean floor are located at mid-ocean ridges, where new oceanic crust is formed through volcanic activity. As the crust spreads away from the ridge, it gets progressively older. This process is known as seafloor spreading.
What evidence can prove that the ocean floor was moving?
Oceanic crust that was farther away from a mid-ocean ridge was older that crust closer to the ridge
Is Mount Kilimanjaro made of continental crust or oceanic crust?
Of course it's continental crust! If it were made of oceanic crust, it would be underwater or some large island starting at the bottom of the ocean floor!
What evidence proved the ocean floor was moving?
oceanic crust that was farther away from a mid-ocean ridge was older than crust closer to the ridge
