Which of the following mountain ranges was not the result of continental-continental convergence? a) appalachians b) andes c) alps d) himilayas

Andes mountain range is not the result of continental-continental convergence.

Explanation:

Between two continental plates when a convergent boundary occurs, the more denser plate is subducted by the less denser one resulting in the formation of various land forms like mountain ranges, earthquakes, volcanoes. This is known as continental-continental convergence. Appalachians are the old mountain ranges formed as a 'result of collision' between North America and Europe continental plates. Alps and Himalayas are also the 'result of continental plate collision'. 'Andes mountains' are a result of oceanic - continental plate collision.
