Mantle Convection and Plate Tectonics (article) | Khan Academy
What is Convection? Convection is the process by which less dense material rises and more dense material sinks. The former are said to be more “buoyant” than the latter, and the vertical forces due …
What is thermal conductivity? (article) | Khan Academy
Dynamic heat conduction involves changing temperature distributions over time, while steady-state heat conduction involves a constant temperature distribution.
Plates moving due to convection in mantle - Khan Academy
When you say the convection current heats up and then say it cools and shifts to the right, do you mean it is shifting the magma to the right, or the new oceanic crust to the right?
