Explanation:
The name of the Pacific Ring of Fire is given to the entire area that comprises the outer edge of the basin formed by the Pacific Ocean and is characterized by its high seismic and volcanic activity concentrated in the form of a ring around its coasts.
This activity is motivated by being a meeting area between tectonic plates. In total, it occupies some 40,000 km of converging edges (the entire American west coast, the Aleutian archipelago, the east Asian coast and Indonesia) along which some plates subduct under others, generating seismic and volcanic events.
Specifically in the Andean region the oceanic plate of Nazca and the continental South American converge. Due to the difference in densities, the oceanic plate, heavier and therefore with less buoyancy, subducts and melts under the lightest, giving rise to a series of phenomena of folding, shortening and elevation of the crust, together with the rise of magmas accompanied by Strong earthquakes produced the friction between both plates, which have lifted the Andean continental volcanic arc.
Answer:
I think you mean the ring of fire.
It is called the "ring of fire" because there are lots of tectonic borders nearby. When there are tectonic borders earthquakes and volcanoes happen so the volcanoes give it the name. When two borders move away from each other magma rises up and creates a volcano. When borders collide the energy suddenly releases causing earthquakes.
