Answer 1

At a plate boundary where the Pacific tectonic plate and the South American tectonic plate are slowly moving away from each other, the natural structure that might be formed is:

A ridge, which is a structure formed due to magma coming out of the mantle and hardening.

This is characteristic of divergent plate boundaries, where tectonic plates move apart, allowing magma to rise from the mantle and create new crust, typically forming mid-ocean ridges.
