the shapes of plates the relative sizes of plates the relative densities of plates the arrangement of plates relative to one another
I gave my students this multiple choice question: A student uses clay to build models of an ocean plate and a continental plate. What characteristic cannot be accurately represented by the models?

Only one answer is correct among these 4 choices:
- the shapes of plates
- the relative sizes of plates
- the relative densities of plates
- the arrangement of plates relative to one another

Could you tell me which one is correct?

the relative densities of plates
