Assertion: radiation zone | /r/HasProperty | stable
Facets:
value: against formation of convection cells
type: TRANSITIVE-OBJECT
Source sentences:
text: The radiation zone is stable against formation of convection cells if the density gradient is high enough, so that an element moving upwards has its density lowered (due to adiabatic expansion) less than the drop in density of its surrounding, so that it will experience a net buoyancy force downwards.
