DISTRIBUTION OF VOLCANOES    

A reveals that the volcanoes of the world are distributed in a specific manner. Most of the volcanoes are near the sea coast or on the Island because there are greater possibilities of percolation of water in these

 areas. The second important area of volcanic activity is that of new fold mountains. The mountain-building forces have left a very thin and weak crust in areas of folding and faulting. The total comes to 522 if the more ancient known eruptions are taken into account.
