How are oceanic and continent crust alike?

Answer 1

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.

Answer 2

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.

Answer 3

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

Answer 4

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.

Answer 5

Both oceanic and continental crust are composed of rocks, but they differ in terms of density and thickness. Oceanic crust is denser, thinner, and younger than continental crust. Additionally, both types of crust are involved in plate tectonics and contribute to shaping the Earth's surface.

Answer 6

because they are just simailar in ways search it on bing, or Google.

Answer 7

the same about oceanic and continental landforms are their mountains

Answer 8

mountain

Answer 9

floor
