Question

You will most likely find isostasy when there is _________________________. A-a balance between the gravitational force of the lithosphere and the buoyancy of the asthenosphere B- a balance between the gravitational force of both the lithosphere and the asthenosphere C- a balance between the buoyancy of the lithosphere and the gravitational force of the asthenosphere D- an imbalance between the gravitational force of the lithosphere and the buoyancy of the asthenosphere

Answer 1

The best answer is D) "Buoyancy" means a capacity to sustain floating objects. The lithosphere(mostly crust) is floating on asthenosphere so the lithosphere exerts a downward force and the asthenosphere is buoyant.
