Answer 1

Answer: yep its the difference in density

Explanation:

Answer 2

Answer:

difference in density

Explanation:

We know that the high central density suggests the earth must be rich in nickel and iron and that much of the core must be liquid. This lower-density air then rises and is replaced by cooler, higher-density air. The result is atmospheric circulation that drives the weather and climate through redistribution of thermal energy.
