The mantle is heated from below (the core), and in areas that are hotter it rises ... with melt (a very hot slurpee), and that kind of material will flow more easily.
It turns out that rocks, along with most other solids, flow by a solid-state, creeping ... This water lowers the melting point of the overlying mantle, causing it to melt.
