Textbook Question
Chapter 7, Problem 45EAP
Change in Formation Properties. Consider either Earth’s size or its distance from the Sun, and suppose that it had been different (for example, smaller size or greater distance). Describe how this change might have affected Earth’s subsequent history and the possibility of life on Earth.
