respond to the following based on your reading.
5. what happens in the theory of isostasy?

plate tectonics

viscoelastic

isostatic equilibrium

asthenosphere

This theory explains how the tectonic plates in the lithosphere able to move freely on the asthenosphere. The lithosphere is less dense than the asthenosphere. There is an equilibrium of the buoyancy between the lithosphere and asthenosphere
