Step-by-step explanation:
The Pacific Ring of Fire is named so because of it's known ring-shaped pattern of Volcanoes. This is all due in part to merging tectonic plates, all resulting in oceanic Volcanoes. It does deserve the name "Ring of Fire" Because of the fact that the volcanoes shoot out fire hot magma, and all of them are arranged in a ring shape around the tectonic plate boundaries.
I hope this helped!
