Answer (2)

The widely accepted theory for the moon's formation is the giant impact hypothesis, which suggests it was created from debris after a Mars-sized body collided with the early Earth. Other theories like co-accretion and capture are less supported by evidence. This explanation aligns with isotopic similarities between the Earth and moon. ;

The moon formed primarily through the giant impact hypothesis, where a Mars-sized body, Theia, collided with early Earth, resulting in debris that coalesced to become the moon. This theory is supported by isotopic similarities between Earth and moon rocks. Other theories like co-accretion and capture have less evidence backing them.
