Explanation

Subduction zones -

Subduction , a geological process which takes place at the convergent boundaries of the tectonic plates where one of the plate can move under another one and is forced to sink by the process of gravity into the layer mantle .  The places where such process occurs are the subduction zones .

The subduction zones are sites with higher presence of volcanoes and earthquake .

Mountain ranges are usually formed at the convergent plate boundaries associated with head - on collision of lithospheric plates .
