Hi there!
The Ring of Fire is (next to the song by Johnny Cash) a chain of I think over 400 volcanos around the Pacific Ocean. The Pacific tectonic plate (under the ocean) is pressed under the continents around it: Asia, Australia, and North and South America. We geologists call this subduction. And where oceanic plates are subducted under continental plates, the water gets squeezed out and at some point the tectonic plate finally starts to melt. And above this squeezing, magma heats up and slowly rises to the surface through cracks and weak zones, and volcanos appear. 🙂
All the best,
Andi

Well that was a *terrible* Johnny Cash joke by Andi…. 😉
The Pacific Ring of Fire is the area all around the edges of the Pacific Ocean (from New Zeland to the Phillipines, to Japan, to Russia, to Alaska to North America and South America). There is an enormous amount of volcanic activity that happens in this area as these areas are where the Pacific tectonic plate pushes under the continents. This movement causes lots of earthquakes to happen and the process causes magma to be produced under the continents which is then erupted onto the surface and produces this “ring” of volcanoes that we see!

What else to say!
The ring of fire is called ring because it has some kind of circular shape. From a geographical point of view it includes almost every piece of coastline in the Pacific with the exception of Australia. As a minor comment Hawaii islands, although, volcanic and situated in the pacific plate are not part of the ring of fire. Contrary they are formed by a deeper process which is known as mantelic plume, molten rock coming from the core-Mantle boundary (very very deep!)
