The Andes mountains running along the western edge of south America were formed by collisions between the south American plate which is continental and the Nazca plate which is oceanic. The collision reasons the continental crust to clasp and form fold mountains which are then scattered with volcanoes produced by melting of Nazca plate as it is enforced down into the earth’s mantle. 

I answer is D) Nazca plate.
Hope this helps.

Isuck at math i am no sorry

F  you double the  force, you double the acceleration, but  if  you double the  mass, you velocity. all bodies accelerate at the  same  rate regardless of size or  mass.
