WebWhat type of plate boundary do the large arrows in Figure 3A show? Expert Answer 100% (4 ratings) Q) Is lithosphere being created, destroyed or neither at this boundary (see … WebEarth’s structure. The Earth has three main layers: The crust ; The mantle ; The core; Crust. There are two types of crust: Continental - a thicker (45-50km), less dense layer (mostly granite); Oceanic - a thinner (6-10km), denser layer (mostly basalt); The crust consists of seven major and several minor tectonic plates; The Mohorovičić discontinuity - is the … cifar-10-python.tar.gz download

WebA convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone. Web1.e. the core is more dense than the mantle 2.b. the inner core is solid nickel-iron 3.b. The Crust and the rigid uppermost Mantle 4.b. the earth's magnetic field is generated by convection in the outer core and the fact that the inner core rotates faster than the outer core 5.b. ocean basins are pulled deep by the action of descending slabs of lithosphere 6.a. … WebThe lithosphere is destroyed at boundaries divergent 3. A trench indicates the location of a divergent boundary. 4. Lithosphere is neither created nor destroyed at boundaries. … dhanywad quotes english
