continental and oceanic crust

Basalt is magma that builds up … The oceanic crust is mainly made out of dark bas… • Oceanic crust is mainly basalt whereas continental crust is mainly granite. The rocks in this layer are made up of light-colored granite rich in minerals and substances like aluminum, oxygen, and silicon. • Oceanic crust is relatively younger than continental crust. Continental Crust The continental crust accounts for 40% of the surface of the Earth. Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate. The oceanic crust is thinner than the continental crust. The density of the continental crust is much less as compared to the oceanic crust. In fact, about 40% of the surface of the earth is made up of this layer. The difference in temperatures is that the image with Continental Crust is deeper into Earth, and the temperature is warmer than the other image. What is the difference between Continental Crust and Oceanic Crust? Geologists suggest that the age of the oceanic crust is around 100 million years, which is still younger than the age of the continental crust. Due to … The continental crust has a density of about 2.6 g/cm3 which helps the continents of the world to stay in one place. It is made up of granite rock which is light in color. Beside above, what causes the difference in temperature between the 2 types of crust? When the heavy oceanic rocks of the Pacific Plate meet the lighter continental rocks of the Australian Plate (along the North Island’s east coast), they dive (subduct) beneath the Australian Plate. It is believed to be made of the products of volcanic lava. The first difference between the two layers comes in the composition of the rocks. Rocks of the oceanic crust tend to be heavier than those of the continental crust. Gray is continental crust, colored is oceanic crust. It is composed of the upper oceanic crust, with pillow lavas and a dike complex, and the lower oceanic crust, composed of troctolite, gabbro and ultramafic cumulates. It has an approximate value of 2.6 g/cm3. The crust overlies the solidified and uppermost layer of the mantle. This is why continental crust floats on the surface of the mantle. The crust and the solid mantle layer together constitute oceanic lithosphere. The continental crust is that part of the crust that makes up the earths surface. This rock is rich in constituents like silicon, aluminum, and oxygen. Oceanic crust is the crust layer found beneath the oceans and contains denser rock than the continental crust. 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. The oceanic crust is the part of the Earth’s crust that creates the seafloor. If you know Earth’s density, they are too buoyant to sink compared to the heavier mantle rocks underneath. Oceanic crust is made up of dense basalt while continental crust is made up of less dense granite. • Oceanic crust is heavier and denser (2.9 g/cubic cm) than continental crust (2.7 g/cubic cm). Continental crust also consists of the shallow seabed close to shores called continental shelves. Continents do something different from oceanic crust.
