How are volcanoes both constructive forces and destructive fores?

Answer:
Volcanoes are both constructive forces, and destructive fores, because
a volcanoes can make a destroy land because when a volcanoes erupt they mostly destroy everything around it but say if a volcanoes erupt in side water the water will cool down the lava and make it in to new land that is how we go islands
mostly every land that you see or walk on was made by a volcanoes or any other forces
