Answer:
The plate boundary is a convergent one where a subduction zone is created.
Explanation:
The Andes are the longest and highest mountain chain in South America, and among the largest ones in the world as well. It is a mountain chain created because of the collision between two tectonic plates and the process is still not over, so the Andes are still growing in size and elevation.
The plates that collide are the Nazca Plate (not the Pacific as it is stated in the question) and the South American plate. The Nazca Plate is a smaller plate and it is mostly made up of oceanic crust, while the South American plate is much larger and is mostly made up of continental crust. The lower and denser Nazca plate moves below the South American plate, thus it subducts, and as it does so, the crust near the plate boundary is pushed up, creating a mountain chain, in this case, that being the Andes.

Answer:
Erosion
Explanation:
At first the fence posts were straight up, but over time that became tilted. The reason fro this is erosion. The erosion managed to remove part of the ground in whist he fence posts have been placed, thus their basis has been weakened, and they have tilted. If the process continues they will soon fall on the ground. Deposition has occurred for sure somewhere, but from this information it is not clear where. There has not been deposition on one side and erosion on other as the fence posts would have been standing straight if that happened. The deposition always occurs as a result of the erosion, but the material can be deposited anywhere from few cm away to several thousands of km away., depending on the transferring medium.
