Boundary between crust and mantle
WebThe boundary between the crust and upper mantle is called the Moho. 3. Figure 19.7: The crust and very top portion of the upper mantle, which also includes the Moho, comprise the lithosphere. The lithosphere is the rigid outer layer of the earth and constitutes the lithospheric plates. The Mantle 1. WebAlong these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate …
