The wear mechanism that removes material by washing or grooving a surface, typically due to fluid flow or particles is called?

Explanation:
Erosion is the wear process where material is removed because a fluid or moving particles wash over or strike a surface. When fast-moving fluid or particles are carried in a flow, they impart energy to the surface, causing impacts or shear that progressively remove material and create grooves or pits. This distinguishes it from abrasion, which is caused by a harder surface scratching another, corrosion, which is chemical dissolution, and creep, which is time-dependent deformation under stress at high temperature. Erosion can involve particle impact, fluid shear, or cavitation-induced jets that over time wear the surface away.
