What is another name for the Circum-Pacific Belt?

A. Pacific Ring of Fire

B. Mediterranean Belt

C. Mount Pinatubo

D. Mount Vesuvius

The famous Ring of Fire, that consists of basically the entire Pacific ocean ... going along California, up over Alaska and Russia, and then back down, along Japan. More of a horseshoe than a ring, really ... but that's nitpicking. 80-90% of the earth's earthquakes and volcanic activity take place along this ring ... hence the name.
