Explanation:
As early people began farming the Fertile Crescent, small villages began to form. With the further development of farming, many of these small communities began to grow into large, complex cities. Located in present day Iraq, the Fertile Crescent is a “half moon” shaped area that lies between two rivers.
They will have to adapt to climate.
An astronaut is able to float slightly on the moon due to the gravity, the gravity being 1.62 m/s² which would be lighter then the earth's which is 9.78 m/s².
In order for the Earth to get larger, more mass would have to be added. Since no new mass is added in the process, It's size doesn't increase.
