The Circle of Fire
The secrets of the Circle of Fire lies somewhere deep into the Earths
formation about 4.5 - 5 billion years ago.
The Circle of Fire is a ring of volcanic mountains that Borders the
coasts of North and South America, along with Asia and Thialand. It also
forms a semi-cirlce from the southern tip of South America to Australia.
The Earth is about 4.5 - 5 billion Years old. Whereas man's recorded
history is only about 5000 years old.(Circle of fire page 3) The Earth is
made up of 3 different layers 1- The Crust, the Crust is the very top layer
of the earth that we live on, it consits of 7 different crustal plates. 2-
The mantle which is the middle layer, This is made of a liquid plastic type
of material called magma, This material is constantly flowing which causes

In 1950 an Expidition from Scripps Institute of Oceanography while
exploring the sea floor off the coast of California discoverd fracture
Zones.(Circle of Fire p 17) These fracture zones run parallel with the
equator from North and South America to Asia down to Thailand as well.
Often these fracture zones are not deep but they run ten to twenty miles
wide. And amazingly the run in an almost equal distance of about 400 - 500
The Circle of Fire is a mysterious place. Though no one knows how it
was formed , scientists believe they are close, They also believe that once
they uncover its secrets, they will be able to answer many of the unsolved
questions of the Earths Formation.
