Which phenomenon causes crustal thinning at divergent boundaries?

💡 Explanation

Mantle convection causes upwelling, thus driving the separation of the lithosphere; this divergence results in crustal thinning because rising mantle material reduces downward pressure rather than increasing crustal density from cooled intrusions.
