Compare and contrast the thickness of the material that makes up ocean basins and continents and how they sit on the mantle. (Which one sits higher on the mantle and why?)
What will be an ideal response?
Answer: Continental material is thicker (up to 70 km) but, in spite of that, sits higher on the mantle because it is less dense (2.7 g/cm3). Oceanic material is thinner (averaging at 7 km), but denser (3.0 g/cm3).
