How do planes appear in a sphere?
Answer and explanation
Correct answer: Like a smooth curved surface
The correct answer is B, like a smooth curved surface. A sphere does not have separate flat planes like a cube or a pyramid. Its surface curves continuously in every direction, with no straight boundary where one plane ends and another begins. In a drawing, changes in value across this continuous surface suggest the sphere’s volume, even though no sharp plane divisions are visible. Option A describes a solid with hard flat faces, option C incorrectly limits the surface to squares, and option D is impossible because every visible three-dimensional form has a surface. Understanding this distinction helps artists observe and shade rounded forms accurately.
