Which outcome relating to tectonic activity follows increased stream sediment load from eroding mountains bordering subduction zones?

💡 Explanation

Increased erosion causes greater sediment deposition on the subducting plate leading to increased pore water pressure. The increased pore water pressure decreases the melting point via flux melting, because lowered melting temperatures allows crustal melts, and melts can propagate rather than being stabilized by a thermal gradient.
