Answer 1

Mountaing building.

Step-by-step explanation:

Mountain building is a process by which, through the movement of tectonic plates over time, undulations and elevations are generated on the face of the earth, which end up originating the mountains that we see today.

Thus, the great mountain ranges and notorious elevations of planet Earth have originated through the collision of different tectonic plates, just as the Andes Mountains originated from the collision of the Pacific Plate and the South American Plate.
