It truly seems martians love to portray their sculptures (at times), utilizing a representation of a domino effect. As if to say, when mars lost it's atmosphere and it's planet destroyed, there was objects hitting other objects in sequence and involved terrible disasters because of it !
Notice the "container" looking sculpture and how it is represented as "morphing". Martians LOVE to morph in some of their sculptures ! It is a true characteristic of they way they tell stories in sculpture diorama-like form !
