Final answer:
The migration of the outer giant planets can affect the sizes and orbits of the inner planets through gravitational interactions.
Step-by-step explanation:
The migration of the outer giant planets can affect the sizes and orbits of the inner planets through gravitational interactions. When the outer giant planets migrate, they can perturb the orbits of the inner planets, causing them to become more eccentric or even destabilizing their orbits and causing ejections. For example, the migration of Jupiter and Saturn may have played a role in shaping the inner solar system by scattering small bodies like asteroids and comets.
