Subducting plates at converging plate boundaries contain water within existing s

Question

Subducting plates at converging plate boundaries contain water within existing surface rock and sediments, which are carried Into the mantle. The water helps the rock melt at a tower temperature. The melted rock is less dense, and works its way upward toward the surface. On the accompanying world map of tectonic plates, converging plates are already indicated by toothed lines. The points indicate the direction of plate subduction. Seduction volcanoes form on the adjacent plate (the plate that Is not subducting).

Explanation / Answer

Generally three typesof margins. They are Divergent, Convergent and Transform Margins. The Subduction zones are formed in Convergent boundaries, these are also known as destructive margins. When two plates are moved towards each other the subduction zones are occured. Generally most of the convergent margins( Subduction Zones) are fomed around the west and north west of pasific ocean( according to map also).

And there is no specific question is asked in map also.
