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.

Jobisdone [24]

Answer:

I believe the answer is 3/4

Explanation:

18 and 24 both have common factors of 6. So you would divide both 18 and 24 by 6. 18÷6=3 and 24÷6=4. 3 and 4 don't have any common factors so this is the lowest it can go and can't be divided anymore. So, 3/4 is the simplest form. Hope I helped! :)
