Well like volcanoes are on land, sea mounts are in oceans (sea mounts are underwater volcanoes) and a deep ocean trench is like a canyon on land. Continental slopes or continental shelves can be similar to cliffs or steep slopes on land.
Mountains formed on the ocean floor are volcanic in origin. The volcanism can be the result of rising magma over a so called 'hot spot' which originates deep in the mantle and penetrates the crust; it can be the result of oceanic to oceanic plate collision, where one (the more dense) plate subducts and melting crust causes eruptions to form volcanic mountains which originate on the ocean floor; mantle material can rise and undergo decompression melting at diverging undersea plate boundaries forming buoyant hot crust creating undersea mountain ridges.
Continental mountains can be volcanic in origin, as well as from the thickening and uplift of crustal material at convergent plate boundaries, and from compressional and tensional forces caused by the movements of tectonic plates.
er, i think that the two crusts are both plates, so the general makeup is the same. They do vary in density though, most likely from varying pressure. point is, they are nearly the same thing, i think, albeit the density
Both are composed of solid rock.
Both plate types are part of the lithosphere.
Both plates float on the asthenosphere.
Oceanic crust is more dense than continental crust.
Oceanic crust is largely basaltic rock; continental crust is mostly granitic.
Only oceanic crust subducts.
Continental crust is thicker than oceanic crust.
Oceanic crust, for the most part, is much younger than continental crust.
the same about oceanic and continental landforms are their mountains

Oceanic and Continental crusts are alike because they both shift and move and grow. They differ by there rock types. Oceanic crust is made up of dense basalt while continental crust is made up of less dense granite.

oceanic crust.
Oceanic crust is significantly denser.
No, it is not an oceanic plate. It is a continental plate but with oceanic crust. Crust is different from plate. A plate is made up of many crust. The crust under the ocean is oceanic crust, while the crust where continent is found is called continental crust. Most of the plates are made up off both continental and oceanic crust. If a plate has continental crusts, then it is a continental plate. Only if a plate is all made up of oceanic crusts, meaning that there is no land on it, then the plate is called oceanic plate. In the world, the major oceanic plates include Pacific Plate, Nazca Plate, Cocos Plate and Philippines Plate. Other are all continental plate.
they both are part of the crust

Oceanic and continental crust contain the same elements. Both also move and shift and grow continuously. They are different because of their density.
Oceanic Crust
Oceanic crust isn't destroyed because it's old; it is, in fact, destroyed due to destructive plate boundaries. This is where a continental plate and an oceanic plate move towards each other. As the oceanic crust is denser, it is pushed under the continental plate. Here it is forced into the mantle of the earth, where it is destroyed due to heat and convection currents.
the continental crust is the plate crust formed under the continent (less density) as opposed to oceanic crustformed under the ocean(higher density)

oceanic crust.
The ocean is never pulled under the continent. Oceanic crust--the rock and some sediments, however, slide under the edges of continental crust and are pushed downward toward the mantle in areas of oceanic to continental plate collisions.
This is referred to as a convergent plate boundary (oceanic-continental). The denser oceanic plate is forced underneath the lighter continental plate by a process called subduction.
