Task: Class Definition Understanding (ontology: Earth_Environment/EnvironmentOntology)

Which of the following definitions best describes 'convergent plate boundary'?

A. A geomorphological feature which is formed where two or more tectonic plates are actively moving along one another in either a sinistral (left lateral) or dextral (right lateral) horizontal direction.
B. A transitional population of migrating mesenchymal cells that derive from somites and that will become dermal cells.
C. A geomorphological feature which is formed where two or more tectonic plates are actively moving towards one another, resulting in deformation of the lithosphere that forces one plate below the other where it melts in the mantle.
D. A geomorphological feature which is formed where two or more tectonic plates are actively moving away from one another, resulting in deformation of the lithosphere that forms rifts or ridges.

Answer: A geomorphological feature which is formed where two or more tectonic plates are actively moving towards one another, resulting in deformation of the lithosphere that forces one plate below the other where it melts in the mantle.
