Question 2

How must the density of oceanic lithosphere compare to the density of asthenosphere in order for the subduction of oceanic plates to occur?

Give a complete answer and explain your reasoning. Hint: note that oceanic lithosphere is the oceanic crust plus the immediate lithospheric mantle below it.

What will be an ideal response?

Answer to Question 1

D

Answer to Question 2

The density of oceanic lithosphere must be higher than the density of asthenosphere in order for plates to subduct. If the lithosphere is denser than the asthenosphere, it will be possible for the lithosphere to sink (subduct). If the lithosphere is less dense than the asthenosphere, it will float on the asthenosphere and will not be able to sink.
