Question

Explain in detail what is constructive,conservative and destructive boundaries and what does each form?? Please answer this because I have a test.

Answer 1

A destructive plate boundary is sometimes called a convergent or tensional plate margin. This occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate. Friction causes melting of the oceanic plate and may trigger earthquakes. Magma rises up through cracks and erupts onto the surface.

An example of a destructive plate boundary is where the Nazca plate is forced under the South American Plate.
