You are watching: How is heat transferred from the core to the crust
So, in the mantle, between the core, where warm is generated, and also the crust, wherein it is at some point dissapated, what proportion of heat is transported via convection and conduction?
It is tho a little known truth that radiation play crucial role in the Earth\"s mantle. Experiments present that mantle-material i do not care transparent come infrared radiation at raising pressures (http://www.esrf.eu/news/general-old/general-2004/earthbadro/index_html).
I would additionally say the the mantle is at this time not understood in a method where approximates of heat-conduction-type matches depth can be that s right made. The heterogeneity of heat transfer (Cold detached subduction-slabs sinking to assorted depths and also hot plumes quickly rising indigenous the D\"\"-layer) renders the question even an ext difficult.
Conduction more than likely is the main technique in the crust, however do not underestimate liquid convection.

Every time you find a warm spring, then that is an instance of liquid convection. Also volcanic eruptions can be taken into consideration convection.
Possibly also larger than these too, over there is vigorous convection that seawater v young ocean crust. This have the right to be seen on figure 10 of Muller eta al Digital Models that the World\"s ocean Crust. This plots depth vs period of s curve. The \"TBL\" heat approximates the curve that is supposed for conductive cooling that the Earth\"s crust. Fact (the bars) are rather different. Although most of this cooling is in young rock, the accumulative effect shows in the enlarge crust. (this plot is make the efforts to demonstrate something else, however I couldn\"t uncover a an excellent example the this classic graph the implied this convection have to exist long prior to Black Smokers were ever before discovered)
