Texture (grain size, shape, sorting) Fine to coarse ..., This secondary process of transport and deposition creates additional glacial landforms. Unlike till, these structures are generally sorted by grain size because the main agent of transport is flowing water. Water flowing along the base of the glacier carries and deposits sediment in a manner similar to a river., The variations of mean grain size, degree of sorting, and the content of the dust fraction (<63 μm) along the south-north transect are illustrated in Figure 2.
