Which process primarily drives the formation of a stepped or terraced cirque morphology in mountainous regions?

💡 Explanation

When cyclical freezing and thawing occur within cirques, progressive glacial plucking and abrasion erodes weaker rock layers, creating a stepped appearance because the glacier's basal sliding removes debris. Therefore stepped morphology results, rather than differential weathering, volcanism or tectonics, elements impacting other landforms or environments over geologic timescales.
