"OLDEST EVENT" (first to form according to the Nebu lar hypothesis) ; SECOND OLDEST EVENT; THIRD EVENT IN SEQUENCE; SECOND YOUNGEST EVENT; "YOUNGEST EVENT" (Last to form in the Solar system, based on the sequence of events listed) LIST OF EVENTS IN FORMATION OF SOLAR SYSTEM (note: the following statements have been radomized) . Within the cloud swirling eddies developed drawing matter towards their centres to form the protoplanets. The planets differentiated into layers as they slowly cooled The protoplanets became solid planets and continued their orbit, governed by the initial spin of the nebula . As the protosun became even hotter, gases were driven off the inner region of the Solar System . As the density of the centre of the accretion disk increased along with its temperature the core of the nebula became the protosun. Note: The statements will be randomized when you go to enter them in the Tests and quizzes tool in Sakai. Although, they are randomized above, they may NOT necessarily show up in the same random order in the Test and quizzes tool
