The Muslims managed to expand from the Arabian Peninsula towards the east fairly easily and this was due to the military power, unification, instability in the east, seeking for security and savior of the people in the east.
The Muslim were unified, and that was a very nice example for the people in the east that if they are unified they will be stronger, and they will also have better lives, and be more secure.
The east was divided into multiple smaller countries where there were constant battles and instability, so the Muslims with their unification propagation were seen as saviors. On top of it, the people in the east were desperate for a new savior, a divine figure, and the Muslims brought that to them.

Answer:
The magma that melts in the upper mantle and erupts at the mid-ocean ridge has a different composition (higher in Ca, Mg, Fe and relatively lower in Si and Al) than the composition of the magma (more Si, Al, Na, K rich in relative terms) that built the continents. Melting different degrees (2%, 5%, 30%) of a rock with a mantle-like composition generates magma of different Al, Si contents. Continents grow at their edges by partial melting of oceanic crust that is being subducted, generating magmas of a somewhat more Si, Al-rich composition than the subducting slab itself. The chemistry and physics of melting a mixture of minerals rather than one homogeneous substance has the wonderful outcome of creating two distinct types of crust:
