Internal Heat of Earth: Viscosity & Convection in the Mantle

Click For Summary
SUMMARY

The discussion centers on the relationship between viscosity and convection in the Earth's mantle, establishing that they are inversely proportional. 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 heat flow. This cyclical process is crucial for understanding mantle dynamics and heat transfer within the Earth.

PREREQUISITES
  • Understanding of thermodynamics and heat transfer principles
  • Familiarity with geological concepts related to the Earth's mantle
  • Knowledge of fluid dynamics, particularly in relation to viscosity
  • Basic grasp of convection processes in geophysical contexts
NEXT STEPS
  • Research the role of temperature in mantle convection models
  • Explore the effects of viscosity on geophysical fluid dynamics
  • Study the implications of mantle convection on plate tectonics
  • Investigate the relationship between heat flow and geological activity
USEFUL FOR

Geologists, geophysicists, and students studying Earth sciences who are interested in mantle dynamics and the thermal processes affecting the Earth's interior.

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 ?
