A)All the planets orbit the Sun in the same direction.
B)All the planetary orbits lie close to the ecliptic.
C)The magnetic fields vary greatly in magnitude and direction.
D)The vast bulk of the solar system's mass lies in the center.

Question

Quizplus · Accepted Answer

The nebular hypothesis explains the formation of the solar system from a rotating cloud of gas and dust. However, it does not provide an explanation for the variation in magnetic fields in the solar system. Magnetic fields are generated by the motion of charged particles within a planet or star, not by the initial formation of the solar system. Therefore, statement C is not explained by the nebular hypothesis. Statements A, B, and D are all explained by the hypothesis – the planets formed from the same rotating cloud, hence they all orbit in the same direction and lie close to the ecliptic, and the vast bulk of the mass in the solar system lies in the central mass of the sun.
