Answer:

Rocks melt at a lower temperature in the presence of volatiles such as water and carbon dioxide.As the cold slab sinks, water is forced out and percolates upward into the overlaying hot, dry mantle rock. This sudden addition of water lowers the melting point of that mantle rock, and it begins to melt.
