Soldiers in World War Two uniforms raising the U S flag. Art expresses many things in culture. How does this image of an American flag being placed at Iwo Jima after the most infamous battle in the Pacific during WWII, use symbolism to commemorate, document, and narrate an event in history?

Ithink the answer is "crash causing a major injury."

Relief sculpture - images are set against a flat background. a coin is a good example: the inscription, the date, and the figure are slightly raised above a flat surface. the ancient egyptians sometimes carved figures into a flat surface.    pro: they take significantly less time to make and do not require as much tools or skills as free-standingcons: not nearly as realistic, as it is not fully 3-d, and does not have the details that a free-standing one does.freestanding sculptures (also called  carved in the round) are not attached to any  background.  they are 3-dimensional  and fully rendered.
