The correct term for the process by which planets form is accretion, which involves the gradual accumulation of matter due to gravity. Choice A is incorrect because while acceleration can play a role in certain processes in the formation of planets, it is not the primary cause. Choice B is incorrect because fusion refers to the process by which stars produce energy, not the formation of planets. Choice C is incorrect because fission involves splitting an atomic nucleus, which has no relevance to planet formation. Choice E is incorrect because while centrifugal force can be a factor in the motions of objects in space, it is not a cause of accretion.
