Earth is the only planet which has actually life, it has actually life integral kind for instance flora and fauna oxygen, water, etc.. Planet is a huge planet which has a big number of geological features. It has landed in part areas, it has actually water in some areas, it has actually aired everywhere the planet.The geological functions of the planet contain a range of mountains, plateau, ocean seas, plains, forests, volcanoes, etc.. The geological functions of any type of place influence the life of world over there.In the sections which are occupied by land have actually different varieties of soil, floor crusts, etc., the density of land is no the same almost everywhere in some areas there will certainly be a slim crust of land and in some parts, there could be a strong crust the land.The sport of crusts, impact the stays of people and animals. According to geology planet has numerous layers of floor under the key crust. In ~ the crust there space two an ext layers, those space Mantle and Core.The main point is the most inner layer of earth which is claimed to it is in the hottest part of Earth over that Mantle is over there which is composed of number of layers and above all that them, there is the crust. The crust is of 2 types; Oceanic crust and also continental crust.
You are watching: Compare and contrast continental and oceanic crust
Oceanic late vs continent CrustThe difference between Oceanic crust and also Continental crust is your composition and properties. Both the them room the uppermost great of Earth but they have actually differences in between them.
Oceanic late is the handmade which covers earth’s oceanic base. It has actually a thickness of 3.0 g/ cm3. That is said to be a slim layer when contrasted to continental crust.The oceanic crust is composed of basalt i beg your pardon is consisted of of black-coloured rock. This absent is fulfilled with minerals like silicon, oxygen, and also magnesium. The oceanic late takes year to kind and it undergoes a process.In number of years this tardy gathers a great of cooled mantle surface ar underside, and the two layers accumulate to sink into the hot molten mantle. And this is how oceanic crust never ever ages because it keeps on recycling.The thickness that the oceanic tardy is 3 come 6 miles or 5 to 10 kilometres. It is composed of different layers; the uppermost layer of oceanic crust is 500 meter thick and consists that lava comprised of basalt.Term used for oceanic crust absent is sima a short kind of magnesium silicates another term supplied for this rocks is mafic, they room high in iron and also magnesium. The ocean floor is the an outcome of smooth pillows of dark and dense basalt rock.There are few ridges whereby it is feasible to go and also feel the thin oceanic crust For example Iceland. There space mid-ocean ridges which room the mountains created under the seawater across the ocean that covers especially the European and the phibìc American plates.The one along which that continues to cover every the oceans and the street It consists is 49700 kilometre. Also the longest mountain range on earth.
The continental crust is the Uppermost layer of earth’s surface and also it constitutes around 40% the Earth. This layer is comparatively stronger and also thicker than oceanic crust.Continental crust is consisted of of granite i m sorry is lighter in colour, and this Rock contains aluminium-silicon and oxygen. The density of continental crust is lower than oceanic crust and also it accounts because that 2.63g / cm3.Due to the difference between the densities that both continental Crust and also Oceanic crust, the balance that continent soil is maintained and both crusts can float ~ above magma. The continent late flows more freely on the magma.The continental crust is thicker and has a distinction in thickness in planes and also mountain areas. In plains, it has a thickness of 20 mile which is roughly 35 kilometres and in mountain areas, this thickness increases up to 40 miles which are around 70 kilometres. The continent crust can be defined as the amalgamation of igneous, sedimentary and Metamorphic rocks Which develops a continent. The areas approximately the shallow sea bed are known as continental shelves.The factor behind the thickness of continent crust is the Compressive pressures related come subduction or a continent collision. The floating capacity of the crust pressures it upwards, the forces of Collisional are balanced by gravity and also erosion. This procedure also helps to form the keel for mountain ranges i m sorry is also the thickest crust of the earth.Continental tardy is responsible because that the land part of Earth. That is the outermost great of the lithosphere, and also it creates the surface ar of the land. The factor behind the low thickness of continent crust is the it floats on the uppermost part of Mantle. Also, lock are consisted of of various rocks which influence their density.
Main Differences between Oceanic Crust and Continental CrustContinental tardy is low in density whereas oceanic crust has a higher density.Continental tardy is thicker, on the contrary, the oceanic tardy is thinner.Continental tardy floats top top magma freely yet oceanic tardy floats top top magma scarcely.Continental crust can not recycle vice versa, oceanic crust deserve to recycle it.Continental crust is comprised of granite salt at the same time oceanic crust is consisted of of basalt rock.

Both oceanic crusts and continental crust forms different surfaces the the earth. Both the them are equally vital for the earth. There are a lot of differences between the two yet yet they aid each other in maintaining the balance that continents.
