Which of the following features was not created by subduction ? ? plz 1.andes 2.alps 3.mariana trench 4.japan

The answer is:

2.Alps

The explanation:

- Alps's mountain chains was the only one which not created by subduction, because Alps formed by collision. The collision is a geologic process in which two plates collide each other, in our example(Alps formation) the Africa tectonic plates collide with the Eurasian tectonic plates and  uplift the crust of the earth  forming the mountain chains.

- but the subduction is a geologic process happened in the regions called subduction zone when one tectonic plate is go under another tectonic plate.

So Alps wasn't created by subduction , but formed by collision.
