Tonal shading refers to what in a sketch or map?

• A. The color palette used in a sketch
• B. The representation of light and shade of a sketch or map
• C. The line weight used to indicate depth
• D. The scale used for measurement

Answer: (B)

Tonal shading is about using light and dark values to convey form and depth in a sketch or map. By varying tone, you simulate how light falls on surfaces, creating highlights and shadows that reveal shape, texture, and relief. On maps, this helps communicate elevation and terrain even without color. This is different from a color palette, which concerns color choices rather than lightness; it’s different from line weight, which uses line thickness to suggest edges or depth; and it’s different from scale, which relates to the size of features. So the representation of light and shade is exactly what tonal shading captures.
