What sediments Loss of edges on sediment grains?

Loss of edges on sediment grains typically refers to the process of abrasion, where particles collide and grind against each other, leading to the rounding of their edges. This occurs during transport by wind, water, or ice, as sediments are moved and reshaped over time. The degree of edge loss can indicate the sediment's transport history and the energy of the environment in which it was deposited. Rounded grains often suggest a longer transport distance or more energetic conditions compared to angular grains.
