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 texture with intersecting lines, using their direction and spacing to suggest shading or the character of a surface. Impasto creates texture by applying thick paint that stands above the canvas. An artist might choose cross-hatching for controlled, drawn detail, while impasto is useful when they want a bold, raised surface that catches the light.
