The subduction that occurred in virginia's piedmont region most likely created a) fossils. b) volcanoes. c) the coastal plain. d) the atlantic ocean.

The subduction that occurred in Virginia's Piedmont region MOST LIKELY created  B) volcanoes.

Explanation:

Piedmont region consists of ancient rocks belonging to the period before the Appalachian Mountains existed. This region is built on the subduction zone.

The igneous rocks are mostly found in volcanoes. These igneous rocks present in the volcanoes were developed from the subduction.

Subduction is the phenomena in which a tectonic plate goes below the other tectonic plate. This results in disturbances and causes earthquakes and volcanoes.

In the Virginian Piedmont region, subduction was responsible for the number of volcanic island arcs.
