Which outcome results from increased freeze-thaw cycles on alpine sandstone?

💡 Explanation

Accelerated scree slope formation occurs because **frost wedging** mechanically breaks down the rock. Water expands upon freezing, exerting pressure that fractures the sandstone. Therefore, weathering increases scree accumulation rather than stabilizing soil, which requires other processes.
