Question

What type of tectonic plate boundary exists between the oceanic and continental crust?

Answer 1

The type of tectonic plate boundary that exists between oceanic and continental crust is typically a **convergent boundary**. In this setting, the denser oceanic plate subducts beneath the lighter continental plate. This process often leads to the formation of ocean trenches, volcanic arcs, and seismic activity. One notable example of this type of boundary is the subduction of the Nazca Plate beneath the South American Plate, which has created the Andes mountain range and the Peru-Chile trench.
