Weegy: In the theory of isostasy, a mass above sea level is supported below sea level, and there is thus a certain depth at which the total weight per unit area is equal all around the Earth; this is known as the depth of compensation. [
]
User: According to the theory of isostasy which statement must be true?
A. The asthenosphere has the same density as the lithosphere
B. The lithosphere has the same density as the core
C. The lithosphere is denser than the asthenosphere
D. The asthenosphere is denser than the lithosphere
Weegy: The asthenosphere is denser than the lithosphere. This must be true according to the theory of isostasy.
