What substitution did Glatzmaier and Roberts make in their model?
A) straight-angled rotation of Earth for its real tilted axis
B) average density in place of specific densities
C) the viscosity of water for the viscosity of the outer core
D) thermal convection for compositional convection

Quizplus · Accepted Answer

Glatzmaier and Roberts substituted thermal convection for compositional convection in their model. This means they based their model on the circulation of heat within the outer core rather than the circulation of different composition materials.
