Answer:
Cross hatching.
Explanation:
Cross-hatching is a sketching technique in which fine parallel lines are drawn to create a texture or an illusion to show shade in the drawing. In such a technique, two layers of right-angled parallel lines are drawn. This sketching technique is used in pencil drawings mostly. To create a darker tone in cross-hatching, more layers of overlapping lines are drawn.
