Answer to Question 1

Water and other volatiles act as salt does to melt ice. Water causes rock to melt at lower temperatures. At a depth of about 100 kilometers, the addition of water lowers the melting temperature of mantle rock sufficiently to trigger partial melting.

Answer to Question 2

Ring of Fire volcanoes are violent. Mount Fuji in Japan and the Cascades are all around the Ring of Fire.
