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 ...

4. Earth's mantle - Wikipedia

   en.wikipedia.org/wiki/Earth's_mantle

   The internal structure of Earth. Earth's mantle is a layer of silicate rock between the crust and the outer core.It has a mass of 4.01 × 10 24 kg (8.84 × 10 24 lb) and makes up 67% of the mass of Earth. [1]

5. 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 ...

6. 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

7. 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]

8. 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.

9. Convection firing on West side of Invest 98-L - AOL

   Convection is firing West of Invest 98-L. It is dealing with dry air and strong winds aloft on the East side. It will be moving away from the wind shear and will continue to move into warm water.
