	A visible separation on a surface that extends through one or more layers. Cracks may be due to stress, pressure, temperatures, or humidity variations or mechanical defects. Cracks are described by the size (hairline, wide) and direction (parallel, radial, spiral, etc.). See for example [[crackle]] and [[crazing]]. Geologic terms for cracks include fault, gap, fracture, and fissure. A crack in a textile is mechanical defect due to a missing filling thread.
