The "solar nebula hypothesis" offers what explanation for the different compositions of these two types of planets? a. during the collapse of the gaseous nebula, most of the material tended to collect far from the sun because of the large centrifugal forces, which provided the necessary material to build the large jovian planets. b. during condensation, the heavier elements tended to sink nearer the sun and, being rare, only provided enough material to build the relatively small terrestrial planets. c. the terrestrial planets were formed near the sun where, because of the high temperatures, only heavier elements were able to condense. d. the large gravitational forces of jupiter tended to prevent planet formation in the inner solar system and eventually attracted most of the material into the region of the jovian planets.
