Which of the following must be balanced for a portion of the lithosphere to reach isostatic equilibrium? A. The buoyant force from the asthenosphere and gravity
B. The densities of the lithosphere and the asthenosphere
C. The isostatic uplift and the crustal rebound
D. The compressive forces of two converging plates

B

Explanation: The isostatic equilibrium occurs when enormous tectonic plates composed of crustal and upper mantle material are able to float on top of the astenosphere, which in turn is composed of denser rock material. In order for such a thing to be achieved the lithosphere and the astenosphere have to have balanced densities between each other. In other words, the density of the material on top, has to be in balance with the density of the material below it, thus to not have any uplift or sinking occurring between them.

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.
