What is the action of making island arc on the margins? |
|
Answer» When two plates of similar nature converge, one plate climbs on another while the depletion of a plate occurs. After this the plate’s front is melted when it breaks into an elongated string. This is called the destructive margins. This molten substance reaches out of weak crust and creates volcanic and island arc. Mountains have been formed as island arc on the margins of ocean plates in the Pacific Ocean. |
