Select the correct answer.
Which layer of Earth is the densest and why is that so?
A. The outer core is densest due to gravitational compression.
B. The outer core is densest due to generation of radiogenic heat.
C. The outer core is densest due to accretion.
D. The inner core is densest due to gravitational compression.
E. The inner core is densest due to generation of radiogenic heat.
Answer (2)
The inner core is the densest layer of Earth due to gravitational compression from the layers above it, leading to high atomic density. It is primarily composed of iron and nickel, which also contribute to its overall density. The immense pressure created by the surrounding layers forces atoms closer together, making the inner core extremely dense. ;
The inner core is the densest layer of Earth due to gravitational compression from the layers above, which forces atoms close together. It is mostly composed of iron and nickel, contributing to its high density. Based on this information, the correct answer is D: The inner core is densest due to gravitational compression.
