earths crust causes it
almost no silica in ocean water but most of its the earths crust.
Plate Tectonics. The crust is in large, irregular plates shuffling around by new rock extruded from the upper Mantle in ocean plate boundaries, balanced by the loss of the fringes of the ocean-floor plates to subduction.
1. New sea-floor is created by the upwelling of magma at mid-ocean spreading centers; old ocean floor is destroyed by subduction at deep sea trenches. 2. The area is a subduction zone. Magma from underground comes up and destroys that crust. That crust is then recycled and the magma cools and hardens. That creates new land, that creates the trenches. Seafloor spreading is in the ocean and happens with convection currents. That is the relationship between. 3. As new seafloor is formed at mid-ocean ridges, the old seafloor is pushed down into trenches at subduction zones.
The crust is the Ocean floor. There is Oceanic Crust, And then There is Continental Crust.
continental crust
No it does not But it is in the atmosphere and earths crust!!
earths crust includes ocean floors and
earths crust causes it
The earths crust its 5-70km deep in the ocean and upto 100km deep at mountain ranges. At certain areas, the crust is unstable due to moving plate tectonics.

a moving portion of earths crust and upper mantle is called a ridge that's when the ocean floor has underwater volcano that erupts
Sodium is found in the Earths crust!! But i don't know about the ocean!! And Sodium is salt!!
crust
Earths crust extend deeper below the continents than below the oceans basins (or at least this is what I think).
the earths crust is 25 miles beneath the continents and 6.5 miles beneath the ocean
