The asthenosphere lies 80-200km below the surface under the lithosphere. Convection also occurs in the asthenosphere. The asthenosphere is mostly made of up rock material (magnesium and iron silicates). The asthenosphere makes up 6% of the mantle and lets the lithosphere move.
Best of Luck!
The answer would be B, The weight of the object on planet A will be greater than the weight of the object on planet B.
This is correct because the force of gravity on planet A pushes down on the mass to make it greater
This is also correct because I got it right on my test, hope this helps.
