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.
Does the fact that ocean crust is older the farther away it is from an ocean ridge support the theory of plate tectonics?
Yes, the fact that ocean crust is older the farther away it is from an ocean ridge supports the theory of plate tectonics. This is because new oceanic crust is formed at ocean ridges through the process of seafloor spreading, where molten rock rises and solidifies, pushing older crust away from the ridge. By observing the age of oceanic crust, scientists can trace the movement of tectonic plates and support the theory of plate tectonics.
What The ocean crust is?
Oceanic crust is the part of Earth's lithosphere that surfaces in the ocean basins.
Compared to landform crust the ocean crust is?
younger
Compared to ocean crust near deep-sea trenches crust near ocean ridges are?
Compared to ocean crust near deep-sea trenches, crust near ocean ridges is generally younger, thinner, and hotter. Ocean ridges are sites of active seafloor spreading where magma rises to create new crust, while deep-sea trenches are associated with subduction, where older, denser crust is pulled back into the mantle. As a result, the crust at ocean ridges is also less dense and more buoyant than the crust found near trenches.
Continental and oceanic crust?
The two parts of the crust that make up the earth. The continental supports land while the oceanic crust is at the bottom of the ocean. - Anonymous
Ocean crust dives below continental crust because?
Ocean crust is denser
What supports the oceans?
Oceanic crust
Why the crust is thinner than the ocean floor?

Crust under the ocean is called?
Crust under the oceans is called oceanic crust.

What evidence in rock supports the theory of seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.
Which part of earth supports life?
The crust
What is ocean crust?
it is basalt or oceonic crust
What is the crust beneath the ocean?
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.
What is the ocean crust?
Oceanic crust is the part of Earth's lithosphere that surfaces in the ocean basins.
