Explain the difference between cross-hatching and impasto in creating a sense of texture. Why would an artist select one over the other?

Answer:

Cross-hatching creates the appearance of texture by layering intersecting lines, often to show shading, form, or roughness on a flat surface. Impasto creates actual texture by applying thick paint that rises from the surface. An artist might choose cross-hatching for detailed, controlled effects, while impasto is useful when they want visible brushwork and a tactile, dimensional surface.
