text: The shadows give is it's face because there is bumps on mars, so that when shadows go a certain direction, it casts shadows and makes it look like a human face on Mars. In the article it says " A few days late NASA unveiled the image for all to see. The caption noted a "huge rock formation...whihc resembles a human head.. formed by shadows giving the illision of eyes, nose, and mouth." The author reasoned it would be a good way to engage the public and atrract attention to Mars." This goes on to prove my next point.
