Abstract
The preceding chapters give an indication of the prodigious, wideranging,and occasionally brilliant efforts of numerous investigators toadd refinements to Earth models giving distributions of the density ρ and related physical properties — k, μ, p, g, etc. — in the Earth’s interior. The refinements made during the period since World War II, though sometimes carrying very important implications outside the main Earth model problem, have mostly been fairly small, the net changes in the numerical estimates of ρ etc. over this period having been less than 5 per cent at most depths. The stage has now been reached where many Earth models are being produced which are, at best, minor variants of others.
