Does a subduction occur in a convergent boundary?

Answer 1

Yes, subduction occurs at a convergent boundary—but specifically when an oceanic plate converges with another plate.

Here’s how it works:

🔁 Convergent Boundary Types:

Oceanic-Continental Convergence

The denser oceanic plate subducts beneath the lighter continental plate.

🌋 Example: Andes Mountains (South America)

Oceanic-Oceanic Convergence

One oceanic plate subducts beneath the other, forming island arcs.

🌋 Example: Japan, Mariana Trench

Continental-Continental Convergence

No subduction occurs here—both plates are too buoyant. Instead, they collide and crumple, forming large mountain ranges.

🏔️ Example: Himalayas

✅ Summary:

Subduction = Yes → Oceanic-continental & oceanic-oceanic boundaries

Subduction = No → Continental-continental boundaries

Answer 2

Subduction is when one of the plates is forced down beneath the other plate at the convergent boundary.
