Solution
The false statement is: "The minimum mass solar nebula approximately accounts for all of the hydrogen and helium that were present in the initial disk but which were not incorporated into the terrestrial planets."
This is false because the minimum mass solar nebula model does not account for all the hydrogen and helium that were present in the initial disk. These light gases, also known as volatiles, were largely lost to space and not incorporated into the terrestrial planets. The model primarily accounts for the solid materials that went into the formation of the planets.

1.Question 1Which of the following is the best explanation of why we have small bodies in the solar system?1 pointNearby planets caused the orbits of forming planetesimals to acquire high velocities and eccentricities, preventing run away growth and leading to shattering impacts.Planetesimal formation in the region of the asteroid and Kuiper belts was delayed until after the gas in the nebular disk had dissipated, preventing these objects from acquiring gassy envelopes.Insufficient mass existed in the region of the asteroid belt and Kuiper belt to allow full sized planets to form.The oligarchs that formed in the region of the terrestrial planets and the asteroid belt slowly merged over ~100 Myr and the oligarchs at the outer range of this region were excited by Jupiter enough to cause impacts to shatter the objects. A similar process took place in the Kuiper belt.Nearby planets caused excitation of the orbits of planets in the region of the asteroid belt and Kuiper belt and these planets collided and their fragments are now the small bodies.
