Final answer:
Oceanic crust is thinner but denser than continental crust - True. The densities of the crusts determine their positions when they collide.
Explanation:
True. The oceanic crust is indeed thinner but denser than continental crust. This difference in density and thickness affects how the crusts interact with the mantle and each other.
When oceanic and continental crust collide, the denser oceanic crust will sink below the less dense continental crust due to isostasy. This sinking is because of the difference in densities between the crusts.
