Upper Mantle Viscosity

TNRTB Archive - Retained for reference information

Exploration of Earth’s upper mantle continues to uncover evidence for supernatural design. Geologists and chemists discovered the sources for variations in the viscosity of the upper mantle: water concentration and mantle temperature. Since the level of variations in upper mantle viscosity must be carefully fine-tuned in order to get the plate tectonics that makes the long-term survival of advanced life possible, such fine-tuning implies additional fine-tuning in the geographical distribution of plate subduction rates and plate boundaries. All of this exquisite fine-tuning of Earth’s mantle is readily explained by an intelligent, supernatural Designer.
