WebThere are two types of crust. Continental crust has a relatively low density and composition similar to granite. Oceanic crust has a relatively high density, especially when cold and … WebThe mechanical layers of the Earth a differentiated by their strength or rigidity. These layers are not the same as the compositional layers of the Earth, such as the crust, mantle, and core, though sometimes the boundaries fall in the same places. You may be wondering how it is that layers of the Earth can be liquid, or ‘plastic’.

WebBecause crust is less dense than underlying mantle, local crustal thinning should produce lowered elevations in the center of a rift (e.g., McKenzie, 1978 ). This puts the center of the rift into relative compression, and this makes continued extension harder. WebThe mantle is not considered magma, because most of it is not liquid. The asthenosphere behaves like a fluid, but it is actually solid. Only a small percentage of the asthenosphere is partial melt (on the order of 2-3%). …
