Which weathering process primarily facilitates the formation of a cirque in alpine environments?

💡 Explanation

When meltwater refreezes in rock fractures within a glacier, frost shattering occurs causing cracks to widen and rock to fracture, while glacial plucking removes loosened rock. Therefore, frost shattering coupled with glacial plucking allows the ice to erode the bedrock creating a cirque, rather than other processes requiring differing materials or climate actions.
