Question

During a field trip, Liu notices that an old marble statue looks different from a new marble statue. The surface of the old statue is rough while the new statue is smooth and shiny. There is a high level of pollution in the area the statues are located. What is most likely the cause of the difference in the way the statues appear?

Answer 1

Over the period of time the old statue loses its shine and gets weathered by chemical and physical process of air and water.

Step-by-step explanation:

• As the statue is made of marble which is sedimentary rocks that get easily impacted by water and wind. It's possible that heavy rainfall and dust pollution might have caused the dullness in the limestone contents of the statue. Which may lead to the erosion of the base or might have disfigured the smooth stricture of the marble.
