Question

question 9 of 10 earth was struck by a mars - sized body about 4.5 billion years ago. what was the result of this collision? a. the beginning of the solar system b. the formation of the asteroid belt c. the formation of the moon d. the beginning of life on earth

Explanation:

The leading theory for the Moon's formation is the giant - impact hypothesis. Earth was struck by a Mars - sized body called Theia about 4.5 billion years ago, and debris from this collision accreted to form the Moon. The beginning of the solar system predates this event. The asteroid belt formed from leftover material during the formation of the solar system and is not related to this Earth - Theia collision. The beginning of life on Earth is a separate evolutionary process not directly caused by this collision.

Answer:

C. The formation of the Moon
