The accretion model that Earth and the other terrestrial planets formed from meteoric material was proposed in 1944 by Otto Schmidt, followed by the protoplanet theory of William McCrea (1960) and finally the capture theory of Michael Woolfson. In 1978, Andrew Prentice resurrected the initial Laplacian ideas about planet formation and developed the modern Laplacian theory. None of these models proved completely successful, and many of the proposed theories were descriptive.
NettetOrigin and evolution. With the rise of scientific inquiry in the Renaissance, investigators attempted to fit theories on the origin of the Moon to the available information, and the question of the Moon’s formation became a part of the attempt to explain the observed properties of the solar system (see Solar system: Origin of the solar system).At first the … haifa protekNettetThe interior of the Earth was thought to be a viscous fluid that could accommodate this sinking and rising.
