Vigorous convection as the explanation for Pluto’s polygonal terrain

Figure 1: New Horizon’s image of Sputnik Planum on Pluto. At a differential stress of 0.1 MPa and a temperature of 30 K, the Maxwell time is about 4 min. Because the effective viscosity depends ...

The Earth's structure

One explanation for plate movements is slab pull. Plates are extremely heavy so gravity acts upon them, pulling them apart. Alternatively, as shown in the diagram, convection currents under the ...
