another question on my study guide

Answer 1

Are you talking the ring of fire a volcanic chain that encircles the Pacific region including Hawaii the entire West coast to Alaska?

Answer 2

You're talking about the "Ring of Fire", the
volcanically active edges of the pacific plate.
The West Coast of America and Canada,
alaska, (NOT Hawaii, thats a 'hotspot`),
East coast of Japan, etc.).
The California earthquakes and Mt St. Helens
eruption are related to this crustal boundary.
