Which process leads to terraces formation along river valleys that are bordered by alluvial plains?

💡 Explanation

When isostatic rebound occurs after glacial unloading, it causes rivers to cut down into their alluvial plains, forming stepped terraces due to the downcutting. Therefore, isostatic reboud is the answer due to the downward river cutting, rather than wind deposition, wathering, and glacial scouring.
