Answer:
viscoelastic
isostatic equilibrium
asthenosphere
this theory explains how the tectonic plates in the lithosphere can move freely on the asthenosphere. the lithosphere is less dense than the asthenosphere. there's an equilibrium of the buoyancy between the lithosphere and asthenosphere
Explanation:
Penn foster
The equilibrium in buoyancy forces between the lithosphere and athenosphere is called isostasy or isostatic equilibrium.
What is theory of isostasy?
The theory of isostasy is a theory which explains that their is graduations equilibrium between layers of the above, the lithosphere and the crust below such that addition or removal of weight maintains buoyancy between the lithosphere and athenosphere.
Due to the thick and viscous material in the asthenosphere, the liquid is called viscoelastic.
Isostatic equilibrium is reached when areas of the lithosphere stop rising.
A change in density occurs as a result of compression of the athenosphere.
Therefore, the equilibrium in buoyancy forces between the lithosphere and athenosphere is called isostasy or isostatic equilibrium.
