Question

where do shield volcanoes usually occur?
at divergent boundaries
at convergent boundaries
at hot spots
at transform boundaries

Explanation:

Shield volcanoes are typically formed over hot - spots where magma rises from deep within the mantle. Divergent boundaries are associated with mid - ocean ridges and different types of volcanism. Convergent boundaries lead to explosive volcanic activity often due to subduction. Transform boundaries are mainly associated with earthquakes rather than typical shield - volcano formation.

Answer:

C. At hot spots
