In terms of density, how are Blocks A and B analogous to oceanic and continental crust?
What will be an ideal response?
Continental crust is less dense and thicker than oceanic crust. Block B is analogous to continental crust and sits up higher in the mantle than oceanic crust. Block A is analogous to oceanic crust because it is denser and thinner than continental crust and therefore sits "lower" into the mantle (this lower elevation is below sea level on Earth).
