Question

According to the nebular theory, which of the following is not a requirement when describing any model of the solar system formation? Where the solid seeds for planet formation come from to include condensation to metals. The location and composition of an asteroid belt. Jovian (outer) planets are dense, rocky, and small, while terrestrial (inner) planets are gaseous and large. All planetary orbits are prograde (revolve from west to east or in a counter-clockwise direction).

Answer 1

Jovian (outer) planets are dense, rocky, and small, while terrestrial (inner) planets are gaseous and large

Answer 2

Answer: Jovian (outer) planets are dense, rocky, and small, while terrestrial (inner) planets are gaseous and large.

Step-by-step explanation:

Nebular theory suggests that sun and planets were formed in Nebula from dust and gases. The molecular cloud of dust and gases in the solar nebula collapsed and started spinning causing the temperature and pressure to rise. The Sun was born at the centered and rest of the material formed a proto-planetary disc from which planets were formed.

Terrestrial planet are rocky planets having metals and silicates formed closer to Sun and Jovian planets are large gaseous planets located beyond the asteroid belt. The debris exists as asteroid belt, Kuiper belt and Oort cloud.

Thus, Jovian (outer) planets are dense, rocky, and small, while terrestrial (inner) planets are gaseous and large. This is a wrong statement which is not required to describe any model of the solar system formation.
