Lithosphere upper mantle
WebAnswer (1 of 9): Main divisions of earth (crust, mantle and core) are based on there compositions. When we consider the subdivisions of earth on the basis of theological properties(how it is responding to deformation) we can consider the crust plus rigid portion of uppermost mantle above low velo... WebThe mantle is Earth’s second layer. The mantle has two main parts, the upper mantle and the lower mantle. The upper mantle is attached to the layer above it called the crust. Together the crust and the upper mantle form a fixed shell called the lithosphere, which is broken into sections called tectonic plates.

It tolerates huge pressure from above and underneath which keeps in the form of tar. It is denser than the lithosphere but constantly moving underneath due to the rotational motion and gravitational force of the planet. WebInstead, it seems that the LT and HT type magmas originated from distinct mantle sources and parental magmas. Geochemical features of the early stage LT1 lavas are indicative of a significant contribution from the enriched continental lithosphere mantle, whereas the compositional shift from LT1 to LT2 reveals a trend from predominantly shallower …
