Question

composite cone volcanoes are often found along what kind of plate boundary?
transform
divergent
seafloor
convergent

Explanation:

Composite cone volcanoes (also called stratovolcanoes) form at convergent plate boundaries. At convergent boundaries, one tectonic plate subducts beneath another, leading to melting of the subducted plate and magma formation that rises to create volcanoes. Transform boundaries involve sliding plates (no subduction/magma for composite cones), divergent boundaries (like mid - ocean ridges) form different volcanic features (e.g., shield volcanoes in some cases), and "seafloor" is not a type of plate boundary. So the correct option is the one related to convergent boundaries.

Answer:

D. convergent
