hatching - a row of lines, all facing in the same direction. More dense and concentrated in the areas that appear darker.

cross-hatching - similar to hatching, except with the addition of criss-crossing lines.

contour-hatching - follows the contour, or curve or outline, of the object. In this case, the hatching is rounded to match the shape of the circle.

scumbling - tiny, squiggly circular lines - sort of like "controlled scribbling"

stippling - placing many, many dots on the paper to indicate shading. Probably the most time consuming of all the methods, but creates some neat effects.
