where are extrusive igneous rocks typically found?\n in a canyon\n in a riverbed\n near a dormant volcano\n…

Brief Explanations:

Extrusive igneous rocks form when magma erupts onto the Earth's surface. Dormant volcanoes were once active and can have areas where such eruptions occurred in the past, making them a likely location for these rocks. Canyons and riverbeds are more related to erosion and sediment - transport processes, and deep under the Earth's surface, intrusive igneous rocks form instead.

Answer:

near a dormant volcano
