Question

giant impact: a giant object impacted early earth and the ejected material formed the moon. the chemical composition of certain elements on the moon and earth would be the same. astronauts brought back moon rocks to help answer how the moon formed. the observations and data about the moon and earth are provided in table 2. table 2. data from the moon and earth data results age the moon is about 4.51 billion years old. the pacific ocean crust is about 200 million years old. orbit the moon and earth both have nearly circular orbits. chemical composition oxygen isotopes found on earth and the moon are similar. select words from the lists to describe which theory best explains the formation of the moon based on evidence from the data provided. the formation of earth’s moon is best explained by the theory based on the data gathered from earth and the moon.

Explanation:

The data shows that a giant object impacted early - Earth and ejected material that formed the Moon, and there are similarities in chemical composition (oxygen isotopes) between Earth and the Moon, which supports the giant impact theory.

Answer:

Giant impact
