Internal Heat of Earth: Viscosity & Convection in the Mantle

AI Thread Summary
The relationship between viscosity and convection in the mantle is characterized by an inverse proportionality. As temperature increases, viscosity decreases, leading to faster convection and higher heat flow. Conversely, lower temperatures result in higher viscosity, which slows down convection and reduces heat flow. This cycle illustrates how temperature fluctuations in the mantle influence its viscosity and convection patterns, ultimately affecting geological processes and heat transfer within the Earth. Understanding this relationship is crucial for comprehending mantle dynamics and the behavior of tectonic plates.

What is the relationship between viscosity and convection in the mantle?
 
Earth sciences news on Phys.org
Inversely proportional I would say.
 
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 ?

Thread 'The Secrets of Prof. Verschure's Rosetta Stones'

(Edit: since the thread title was changed, this first sentence is too cryptic: the original title referred to a Tool song....) Besides being a favorite song by a favorite band, the thread title is a straightforward play on words. This summer, as a present to myself for being promoted, I purchased a collection of thin sections that I believe comprise the research materials of Prof. Rob Verschure, who at the time was faculty in the Geological Institute in Amsterdam. What changed this...
