What is the relationship between viscosity and convection in the mantle?
 
Earth sciences news on Phys.org
I wanted to know a bit more... actually i read about a cycle somewhere which goes like this... high temperature > low viscosity > faster convection > higher heat flow > low temperature > high viscosity > slower convection > slower heat flow > high temperature. How could this be related to the mantle ?
