Question

These are blank and do not move with tectonic plates submerged fixed rotating undetectable

Answer 1

It seems you might be describing "hotspots." Hotspots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. They are typically stationary and do not move with tectonic plates. The magma from hotspots creates volcanoes, which can appear in chains as the tectonic plates move over them, such as the Hawaiian Islands.

If you meant something different, please provide more context or clarify your question!
