hope this help:)
The answer to the question, How does density affect the organization of earth is A : The densest material is closest to the center
The earth is made up of different layers namely,
The crustThe upper mantleThe lower mantleThe outer core andThe inner core.Each layer goes from topmost to inner most and the density of each layer increases as we moves closer to the center of the earth.
So, the densest material is closest to the center.
So, the answer to the question, How does density affect the organization of earth is A : The densest material is closest to the center
