The denser plate
Explanation:
When two plates forms a subduction zone, the denser plate will subduct and dive into the underlying mantle below.
Subduction zone occurs along a convergent margin when two plates of different densities collides.
- When two plates of different densities collides, the denser plates subduct.
- This is because the density of the mantle below is less than its own density.
- Most times, oceanic plates usually subduct during plate convergence.
- Oceanic plates are denser compared to continental plates.
