Want this question answered?
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
Basalt is the dominant rock in the ocean crust. And I assume Granite is dominant for continental crust.
the convergent boundry type is determined by the types of plates. There are Continent - continent plates converging this forms mountains. Then there a Oceanic crust and continental crust colisions which form subduction zones and volcanic activity on the continents side. Lastly there are Ocean - Ocean plate collisions where the hotter and younger ocean floor obducts onto the older floor.
The deep ocean floor and submarine sand reefs are all made up of limestone environment. Limestone is a sedimentary type of rock that can be found in many places. It falls to the ocean floor when tides rise and fall.
Divergent plate boundaries are often found on the ocean floorâ??s crust. These are the type of tectonic plates that produce volcanoes and rifts.

Yes, there are two types of crust on the Earth, oceanic and continental. The crust under the oceans is, of course, oceanic crust which has more mass than continental crust. Each type is formed from plates of different size and shape.
Continental crust.
New ocean floor is created at mic-ocean ridges which are divergent plate boundaries.
All three rock types are found in continental crust, with a preponderance of granitic type igneous rock.
The crust is divided into two types: oceanic crust and continental crust. Oceanic crust, found under the ocean floor, is made of dense rocks such as basalt. It is about 7 kilometers (4 miles) thick. Continental crust, found under land masses, is made of less dense rocks such as granite.
