What types of rock make up the continental crust?
granite
What are the two types of crust and which rocks make up each crust?
there are two types of crust such as the oceanic crust and the continental crust, the oceanic crust is thinner and more dense than the continental crust and is constantly being recycled via subduction upon collisions with Continental crust, and creating at mid-ocean ridges. x
Granite is a low-density rock that makes up the what crust?
Granitic rock forms the majority of the continental crust.
What are the primary rock types that make up ocean and continental crust?
Basalts and granites.
The continental crust is formed primarily of which type of rock?
The continental crust is primarily composed of a type of rock called granite. Granite is a light-colored, coarse-grained igneous rock that forms from the cooling and solidification of magma beneath the Earth's surface. It is one of the main rock types that make up the continental crust.
What is the dominant rock type in the ocean crust and in the continental crust?
The dominant rock type in ocean crust is basalt, which forms from solidified lava. In continental crust, the dominant rock type is granite, which forms from the cooling and solidification of magma beneath the Earth's surface.
How are oceanic crust and continental crust different?
Oceanic crust is denser and thinner than continental crust. Oceanic crust is primarily made up of basalt rock, while continental crust is composed of lighter granite rock. Additionally, oceanic crust is constantly being created and destroyed through seafloor spreading and subduction processes, whereas continental crust is relatively stable.
What is the defitition of continental crust?
The continental crust is the basis of the continents. It is the layer of rock, which is mostly granitic, that forms the continents and continental shelves.
Is the continental crust made of igneous rock?
The continental crust is primarily composed of igneous, sedimentary, and metamorphic rocks. Igneous rocks do make up a significant portion of the continental crust, especially in the form of granite and basalt.
What are the two layers of the continental crust called?
The 2 layers of the continental crust are oceanic crust and the land crust
How does the density of oceanic crust differ from that of continental crust?
Oceanic crust is denser than continental crust because it is primarily composed of basalt, which is a mafic rock with a higher density than the felsic rocks that make up continental crust. Additionally, oceanic crust is thinner and younger than continental crust, contributing to its higher density.
What type of rock is found in continental crust?
All three rock types are found in continental crust, with a preponderance of granitic type igneous rock.
