Possible Convection in Lunar Interior) under these conditions are shown on Figures 8–2 and 8–4. If so, however, it is reasonable to inquire as to whether such material would be susceptible of actual . over time intervals comparable with the age of the Moon; but before attempting to answer this question, let us inquire first about a pos
