from article Moho (Mohorovicic discontinuity)

Characteristics of waves traveling along the Moho. (a) Schematic cross section of the continental crust and upper mantle showing typical wave paths from a source of direct waves traveling near the surface of the crust, refracted waves traveling…

Contour map of Moho depth in the United States. Contour values are given in miles (kilometers). (After R. J. Allenby and C. C. Schnetzler, United States Crustal Thickness, Tectonophysics, 93:13–31, 1983)

Image

from article Plasma (physics)

Approximate number densities (n) and temperatures (T ) of some typical plasmas. The temperature is measured in electronvolts (eV), with 1 eV = 11,605 K. The region above and to the left of the diagonal line represents strongly coupled plasmas (nλD3…
