Question

a scientist claims that the majority of the volcanoes on earth occur on plate boundaries. how can this claim be further supported?volcanoplate boundarythe majority of volcanoes occur on plate boundaries between oceanic plates and continental plates where subduction occurs.the majority of volcanoes occur on plate boundaries between two oceanic plates where hot spot formation occurs.the majority of volcanoes occur on plate boundaries between two continental plates where upliftment occurs.the majority of volcanoes occur on plate boundaries between oceanic plates and continental plates where earthquakes also occur.

Explanation:

The map shows volcanoes concentrated along plate boundaries. Subduction zones (where oceanic plates dive under continental or other oceanic plates) are the primary site of volcanic activity, as the subducting plate melts and rises to form volcanoes. The first option correctly identifies that most volcanoes occur at oceanic-continental plate boundaries with subduction, which aligns with the distribution shown. Hot spots form volcanoes away from plate boundaries, continental-continental convergence rarely forms volcanoes, and earthquake occurrence alone does not explain volcanic formation at boundaries.

Answer:

A. The majority of volcanoes occur on plate boundaries between oceanic plates and continental plates where subduction occurs.
