Answer:
Oceanic plate
Explanation:
The oceanic plate is the thinner but denser plate. At a convergent margin, this plate is known to subduct under the lighter continental plate.
Oceanic plates have an average thickness of about 6km. They are rich in ferromagnessian minerals. These minerals are much denser than those of the silicates that make up the continental plate.
- Oceanic plates produce volcanic rocks especially basalts when they melt.
- They have a density of 3.0g/cm³ whereas continental plates have a density of 2.7g/cm³
