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 using intersecting lines that vary in density and direction. Impasto creates actual raised texture by applying paint thickly to the surface. An artist might choose cross-hatching for a drawing or when suggesting texture with lines, while impasto is useful when the artist wants the brushstrokes to be physically visible and tactile.
