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. Internal structure of Earth - Wikipedia

   en.wikipedia.org/wiki/Internal_structure_of_Earth

   The pressure at the bottom of the mantle is ≈140 GPa (1.4 Matm). [24] The mantle is composed of silicate rocks richer in iron and magnesium than the overlying crust. [25] Although solid, the mantle's extremely hot silicate material can flow over very long timescales. [26] Convection of the mantle propels the motion of the tectonic plates in the

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 ...

5. 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.

6. Lid tectonics - Wikipedia

   en.wikipedia.org/wiki/Lid_tectonics

   Many characteristics of a planetary body influence the presence and degree of lid tectonics. The temperature of a body's core–mantle boundary, and the presence of water, strongly affect the rheological, composition, and thermal diagnostics of lid tectonics. The lid will not participate in the underlying convection of the mantle.

8. Mantle (geology) - Wikipedia

   en.wikipedia.org/wiki/Mantle_(geology)

   The silicate mantle of the Earth's moon is approximately 1300–1400 km thick, and is the source of mare basalts. [4] The lunar mantle might be exposed in the South Pole-Aitken basin or the Crisium basin. [4] The lunar mantle contains a seismic discontinuity at ~500 kilometers (310 miles) depth, most likely related to a change in composition. [4]

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.
