Over decades, which coastal change occurs when differential weathering affects a stack?

💡 Explanation

Arch formation occurs when wave action and erosion preferentially erode weaker layers, exploiting weaknesses inherent to the geology through differential weathering; therefore, arches form rather than even erosion, because of variations in rock resistance.
