Answer:

a.The elements of art are the building blocks of an artwork: color, line, shape, form, value, texture, and space. They are the tools artists use when creating an artwork. The principles of design are how those building blocks are arranged: contrast, rhythm, proportion, balance, unity, emphasis, movement, and variety.

b.In any work of art there is a thought process for the arrangement and use of the elements of design. The artist who works with the principles of good composition will create a more interesting piece; it will be arranged to show a pleasing rhythm and movement.
