Fold mountains are created when two tectonic plates collide and compress, forcing the land upwards into a series of folds and ridges. Plate boundaries are the areas where tectonic plates meet and interact with each other. Therefore, the connection between fold mountains and plate boundaries is that most fold mountains are found at or near plate boundaries, where the tectonic activity is most intense. Examples include the Himalayas, Andes, Rockies, and Alps, which are all located at or near plate boundaries.
