Areas where tectonic plates meet up but do not fit neatly into a category, and are ill-defined, are called question 2 options: transform boundaries plate transformation boundaries plate boundary zones multi-boundary zones

Option (3)

Explanation:

Plate boundary zones refer to those regions where the floating tectonic plates form a convergent, transform or a divergent type of plate boundary. This covers a large distance, ranging from about tens of kilometers to hundreds of kilometers. The formation of subduction one, oceanic trenches, large mountain belts, and occurrences of earthquakes are associated with the plate boundary zones.

These zones are the areas where the tectonic plates move against one another but they do not fit correctly into a distinct category.

Thus, the correct answer is option (3).
