no - it is a set boundary in the middle of the Andes.

A natural boundary is a boundary that is viewed from a physical factor like a mountain, river, or other land form/waterway. A political boundary is a boundary that is man made or decided by people. For example the state border is a political boundary.
The North American and Pacific Plate boundary is an example of a convergent plate boundary, specifically an oceanic to continental convergent plate boundary.
Oceanic crust is destroyed at a convergent boundary where subduction occurs. An example includes the boundary between the Nazca and South American plate on the west coast South America.
A natural boundary is often times a body of water such as a river. Between the US and Mexico, part of the boundary between these two countries is the Rio Grand River. A political boundary is one created by a treaty or some type of political agreement between two countries. For example, the Dominican Republic and Haiti are on the same island. The boundary between them is a political one established when France ruled Haiti and Spain ruled the Dominican Republic.
Yes. An example is the San Andreas Fault, a transform boundary between the Pacific (oceanic) and the North American (continental) plates.
Andes, convergence between South American Plate and Pacific Plate
Im just going to guess that its a boundary that nature provided, but and example is an ocean, a river, and a mountain.
Relict boundary is a boundary that has ceased to function, but its imprint can still be detected on the cultural landscape An example would be East and West Berlin.
The Himalayan mountains.
