Explanation:
Detailed explanation-1: -Therefore, the layering of Earth is a result of gravitational pull. The densest layer (inner core ) is at the center and the least dense layer (crust) is the outermost layer.
Detailed explanation-2: -The mesosphere is extremely cold, especially at its top, about −90 degrees C (−130 degrees F). The air in the mesosphere has extremely low density: 99.9 percent of the mass of the atmosphere is below the mesosphere.
