The thickest layer of the continental crust is at the top of mountain ranges like the Himalayas. Continental crust is the surface that forms land masses, and oceanic crust is the surface found under the ocean floor. The continental crust is much thicker when compared to the oceanic crust. It is the outermost layer of the lithosphere, and it forms the surface of the land. The continent crust flows more freely on the magma. Basalt is magma that builds up in time and gets broken down through the process of subduction. The oceanic crust is the part of the Earth’s crust that creates the seafloor. Among the most crucial properties of these layers is their density. Both of them are the uppermost layer of Earth but they have differences between them. Earth is the only planet which has life, it has life integral form for example flora and fauna oxygen, water, etc.. Earth is a large planet which has a large number of geological features. Continental crust is made up of granite salt on the other hand oceanic crust is made up of basalt rock. An oceanic crust is lots denser and thinner. And this is how oceanic crust never ages because it keeps on recycling. Let’s take a look at the differences between the two types of crust. • Continental crust is made up of landmasses, whereas oceanic crust is the floor of the oceans. The planet Earth is covered by a crust, which is divided by geologists into the oceanic crust and the continental crust. It is high in silica and magnesium, that is why called SIMA. • Oceanic crust is relatively younger than continental crust. Although both go through changes during the subduction process, the continental crust is rarely completely destroyed during subduction. Continental crust also consists of the shallow seabed close to shores called continental shelves. It has landed in some areas, it has water in some areas, it … continental crust is thicker, on the contrary, the oceanic crust is thinner. The oceanic crust takes years to form and it undergoes a process. The geological features of any place affect the life of people over there. Difference between Oceanic and Continental Crust, The density of the oceanic crust is higher than that of the continental crust. There are a lot of differences between the two but yet they help each other in maintaining the balance of continents. How is oceanic crust different from continental crust? Earth is the only planet which has life, it has life integral form for example flora and fauna oxygen, water, etc.. Earth is a large planet which has a large number of geological features. The floating ability of the crust forces it upwards, the forces of Collisional are balanced by gravity and erosion. Continents do something different from oceanic crust. As this partial melting process occurs at the mid-ocean ridges, the oceanic crust increases in density. Both oceanic crust and continental crust are less dense than the mantle, but oceanic crust is denser than continental crust. In several years this crust gathers a layer of cooled mantle surface underside, and the two layers accumulate to sink into the hot molten mantle. If you know Earth’s density, they are too buoyant to sink compared to the heavier mantle rocks underneath. Let’s dig a bit deeper into Earth’s geology, igneous, sedimentary, and metamorphic rocks, lithosphere sits on the plasticky asthenosphere layer. It makes up all of the Earth's continents and is much less dense than the oceanic crust. The geological features of the earth contain a variety of mountains, plateau, ocean seas, plains, forests, volcanoes, etc.. This is why continental crust floats on the surface of the mantle. The variations of crusts, affect the lives of people and animals. When a rock goes through a partial melting process, the rock that doesn't melt maintains its original properties while the melted area either recycles or loses some of its original properties, allowing it to maintain the density level. In simple terms, density can be defined as the heaviness of a substance. Continental crust is older, lighter and cannot be destroyed. Copying is allowed with active link to TheyDiffer.com. Where is the oldest and youngest rock on Earth? It's a bit thicker than oceanic crust, which is made up of layers of basalt. There are few ridges where it is possible to go and feel the thin oceanic crust For example Iceland. Please read the Terms of Use and Privacy Policy. This is why scientists study the continental crust to determine the age of the Earth or how long a formation has existed because this layer of crust rarely goes through a total destructive process. Oceanic plates carry the continental plates around the outdoors of the Earth. Scientists refer to the oceanic crust materials as "siam," which is silicate and magnesium. The evolution of land life from marine life was made possible by this type of crust. Continental crust is the layer of the Earth that's readily seen from space. Magma shoots up through gaps in the ocean’s floor here. It is often distinguished from the mantle by having more silica. The reason behind the low density of Continental crust is that it floats on the uppermost part of Mantle. The oceanic crust, on the other hand, may completely melt away into rising magma, creating brand new rock. Due to a lower density, this layer of crust is able to float on the surface of the water. Both types of crusts form during plate tectonics, where tectonic plates crash into each other or rip apart to create new layers of rock. In the portions which are occupied by land have different types of soil, land crusts, etc., the density of land is not the same everywhere in some places there will be a thin crust of land and in some parts, there might be a strong crust of land. The peculiar property of the oceanic crust is that it can actually “recycle.” Basalt and other minerals that make up the oceanic crust get melted in the mantle of the planet, once the oceanic crust reaches it. The other reason is the difference in composition between the Oceanic and Continental crusts. Home » Science » Difference Between Oceanic Crust and Continental Crust (With Table). Due to the granite it is made up of, it cannot be as easily disrupted as the oceanic crust. Less dense layers float on top of denser ones such as the mantle. Differences in Rock Material Different types of granite make up the continental crust and scientists often refer to it as "sial," which means silicate and aluminum. Together, these layers make up the uppermost part of the earth t… Although both go through changes during the subduction process, the continental crust is rarely completely destroyed during subduction. Also, they are made up of different rocks which affect their density. Some scientists estimate that some areas of continental crust could be as old as the Earth. Density Differences The difference between oceanic and continental crust rock material is the density and explains why the oceanic crust is beneath the ocean's surface while continental crust can rise into the Earth's atmosphere in the form of mountain peaks. Like the oceanic crust, the continental crust is destroyed by the subduction process but goes through more partial melting processes than the oceanic crust, allowing it to maintain its lower density and remain above the ocean.
