Cracking is the wearing or grinding away of material by water laden with sand, gravel, or stones.

• A. True
• B. Not Applicable
• C. Both
• D. False

Answer: (D)

Cracking is a fracture process caused by stress, not wear from sediment-laden water. The description given matches abrasion or erosion, where hard particles in the flowing water grind or grind away material, or where fluid flow removes material over time. Cracking would show as a fracture or fissure in the material due to tensile, bending, or cyclic stresses, not as a surface worn smooth or gouged by particles. So the statement is not correct because it mixes up a wear mechanism with a crack formation mechanism.
