The material that was on the outside cooled quicker, but this was the result, not the cause.
The answer is
<span>2) Gravity caused more-dense material to move toward the center of each planet.</span>
Answer:
Density, Temperature, and Pressure all increase. The pressure at the boundary between the mantle and the outer core of Earth is inferred to be approximately... 1.4 million atmospheres. What is the inferred temperature at the boundary between Earth's stiffer mantle and outer core?
