Erosive Wear

Erosive wear takes place when hard solid particles impact on a surface (Tilly, 1977; Hutchings, 1992; Charles et al., 1997) and material loss due to erosion E is measured as the ratio of the mass of removed material with respect to the mass of erosive particles. Erosive wear is due to the impact of hard particles on surfaces. The erosion processes …

Weathering and erosion (article) | Khan Academy

Chemical weathering is the creation of sediment through chemical means. For example, acid rain can react with rocks, dissolving them. Erosion occurs when water transports sediment from one place to another. For example, a river can carry mud downstream. In general, water has more erosional power when it flows faster and has more volume.
