| Description | In view of the principle of actualism the early history of the earth must be explained on the basis of present-day natural phenomena and the basic Laws of Nature. The study of the solar system leads to the conclusion that the planets were formed as by-products when the sun developed from a rotating cloud of cosmic gas and dust. The protoplanets or planetesimals could have accreted as a result of mutual collisions, during which they could have become partly molten so that they could differentiate into a crust, a mantle and a core on the basis of differences in density. Op grond van die beginsel van aktualisme moet die vroee geskiedenis van die aarde ontrafel word aan die hand van huidige natuurverskynsels en die basiese natuurwette. Die studie van die sonnestelsel lei tot die gevolgtrekking dat die planete as neweprodukte ontstaan het toe die son uit ’n roterende wolk van kosmiese gas en stof gevorm het. Die protoplanete of planetesimale kon vanwee onderlinge botsings groter gegroei en ook gedeeltelik gesmeit het, sodat hulle gedifferensieer het in ’n kors, mantel en kern op grond van digtheidsverskille. | |
