. “ [The following is] a somewhat surprising outcome considering the size of the Moon and the assumption that most of its heat energy had been lost. ... These unexpectedly high lunar [heat flow] values seem to indicate the Moon’s interior is much hotter than most thermal models had anticipated. If the temperature gradient in the lower regolith is extrapolated to great depths, the lunar interior would appear to be at least partly molten—a condition contradicted by other evidence.” Nicholas M. Short, Planetary Geology (Englewood Cliffs, New Jersey: Prentice-Hall, 1975), p. 184.

. The unexpectedly large heat flow may be a consequence of large impacts occurring on the lunar surface at the time of Earth’s global flood. [See Figure 145 on page 268.]
