First of all, you need to know what the lithosphere is. It is defined as the crust and part of the mantle. The lithosphere must do its best to stay in isostatic equilibrium. So sometimes there are changes in this balance. When the crust builds up from mountain building, the mantle must move to allow for that. If the crust thins due to erosional or tensional forces, the mantle thickens in response. Obviously I am oversimplifying this. Look up the Pratt hypothesis and the Airy hypothesis on lithospheric changes.
