At a convergent boundary, you would expect to find folded mountains or volcanic mountains, depending on the type of plates involved. Here's a breakdown:

* Folded Mountains: When two continental plates collide, they push against each other, causing the land to buckle and fold. This creates mountain ranges like the Himalayas, the Alps, and the Andes.

* Volcanic Mountains: When an oceanic plate subducts (slides) beneath another plate, the process melts the oceanic plate and creates magma. This magma rises to the surface and erupts, forming volcanic mountains. Examples include the Cascade Range in North America and the Andes Mountains in South America.

In summary:

* Continental-Continental Convergence: Folded mountains

* Oceanic-Continental Convergence: Volcanic mountains

* Oceanic-Oceanic Convergence: Volcanic island arcs
