01.01.1987· The blocks, which fit initially like a jigsaw puzzle, gradually thin and corrode, breaking up into much smaller fragments. Ultimately, all the loosened and weathered material is removed by wind and, after the underlying bedding is exposed, the cycle recommences with further splitting and separation along another bedding plane.

On the persistence of 'weathering' - ScienceDirect

May 01, 2012· Such a movement is likely to vary in magnitude between, for example, the processes of chemical modification and mechanical crack widening by tree roots, but there seems to be little point in debating this in absolute terms. Perhaps the only functional separation of weathering and mass movement (wasting) rests with the focus of attention.

3. Weathering | Geological Introduction

Since the weathering will be most intense at the block corners, these, with time tend to become rounded and the decomposition more concentric, causing a pealing effect like an onion (exfoliation). This is well illustrated in figure 36. where one can see examples ranging from blocks with barely rounded edges, to blocks that are almost spherical and blocks where the exfoliation is quite distinct.
