In the event that two tectonic plates collide, they structure a convergent plate boundary. Typically, one of the converging plates will move underneath the other, a procedure known as subduction. Profound trenched are included frequently where tectonic plates are being subducted and earthquakes are normal. As the sinking plate moves further into the mantle, fluids are discharged from the rock making the overlying mantle to somewhat melt. The new magma ascents and may emit fiercely to frame volcanoes, regularly forming curves of islands along the convergent boundary.
