2. Mantle convection - Wikipedia

   en.wikipedia.org/wiki/Mantle_convection

   On Earth, the Rayleigh number for convection within Earth's mantle is estimated to be of order 10 7, which indicates vigorous convection. This value corresponds to whole mantle convection (i.e. convection extending from the Earth's surface to the border with the core). On a global scale, surface expression of this convection is the tectonic ...

3. Earth's mantle - Wikipedia

   en.wikipedia.org/wiki/Earth's_mantle

   The movements of the lithosphere and the underlying mantle are coupled since descending lithosphere is an essential component of convection in the mantle. The observed continental drift is a complicated relationship between the forces causing oceanic lithosphere to sink and the movements within Earth's mantle.

4. Earth's internal heat budget - Wikipedia

   en.wikipedia.org/wiki/Earth's_internal_heat_budget

   Earth heat transport occurs by conduction, mantle convection, hydrothermal convection, and volcanic advection. [15] Earth's internal heat flow to the surface is thought to be 80% due to mantle convection, with the remaining heat mostly originating in the Earth's crust, [16] with about 1% due to volcanic activity, earthquakes, and mountain ...

6. Large low-shear-velocity provinces - Wikipedia

   en.wikipedia.org/wiki/Large_low-shear-velocity...

   Directly above the core–mantle boundary is a 200-kilometer (120 mi) thick layer of the lower mantle. This layer is known as the D″ ("D double-prime" or "D prime prime") or degree two structure. [6] LLSVPs were discovered in full mantle seismic tomographic models of shear velocity as slow features at the D″ layer beneath Africa and the ...

7. Convection - Wikipedia

   en.wikipedia.org/wiki/Convection

   Mantle convection occurs at rates of centimeters per year, and it takes on the order of hundreds of millions of years to complete a cycle of convection. Neutrino flux measurements from the Earth's core (see kamLAND ) show the source of about two-thirds of the heat in the inner core is the radioactive decay of 40 K , uranium and thorium.

   The title of Cashman’s 1981 creation, “Talkin’ Baseball,” became a part of the sport’s lexicon. Its words always come back to three men: Willie Mays, Mickey Mantle and the Duke Snider.

9. Convection (heat transfer) - Wikipedia

   en.wikipedia.org/wiki/Convection_(Heat_transfer)

   In many real-life applications (e.g. heat losses at solar central receivers or cooling of photovoltaic panels), natural and forced convection occur at the same time (mixed convection). [4] Internal and external flow can also classify convection. Internal flow occurs when a fluid is enclosed by a solid boundary such as when flowing through a pipe.
