Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
Change in Formation Properties. Choose either size or distance from the Sun and suppose it had been different for Earth. (For example, suppose Earth had been smaller in size or at a greater distance from the Sun.) Describe how this change might have affected Earth’s subsequent history and the possibility of life on Earth.
