Quizplus · Accepted Answer

Mars appears reddish due to iron oxide (rust) on its surface, and it has dark markings (such as the famous "Mars face") that are believed to be caused by volcanic activity or dust storms. Its rotation is visible as it appears to move across the night sky, and it has white icy polar caps that have been observed to change in size with the seasons.
