On the basis of seismic refraction data, we divide the crust into type sections associated with different tectonic provinces. Each shows a three-layer crust consisting of upper, middle, and lower crust, in which P wave velocities increase progressively with depth. There is large variation in ...
What are the layers of the Earth's crust? Which layer of the Earth contains the crust? What does the crust do for the Earth? How many elements make up the majority of Earth's continental crust? What was the Earth Crust Displacement?
Above the mantle isEarth's crustwhich is a part of the mechanical layer called the lithosphere, and the outermost layer of Earth. The crust is the lightest of the layers, composed of the lightercontinental crustand the denseroceanic crust. Earth's crust is fragmented intoplatesthat are moved...

What are characteristics of the oceanic crust and the continental crust? Both the continental crust and oceanic crust make up the outermost layer of the Earth. These are the least dense layers of Earth, with continental being less dense than oceanic. Both continental and oceanic crust have a hi...
s oceans.The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The lithosphere is about 100 kilometers thick. The definition of the lithosphere is based on how earth materials behave, so it includes the crust and the uppermost mantle, which are both ...
Learn about the oceanic crust, including the oceanic crust definition, oceanic crust thickness and density, oceanic crust composition, and other...
Features of the Lithosphere Lesson Summary Register to view this lesson Are you a student or a teacher? FAQ What are the three layers of the lithosphere? The lithosphere is made up primarily of 2 main layers, not 3. The top layer of the lithosphere is the Earth's crust. The bottom laye...
