Question

The Earth surface is not uniform explain

Answer 1

Explanation:

The Earth is not a uniform sphere, but has regions of varying density. Consider a simple model of the Earth divided into three regions-inner core, outer core, and mantle. Each region is taken to have a unique constant density (the average density of that region in the real Earth)

A) Use this model to predict the average density of the entire Earth.

B )The measured radius of the Earth is 6371km and its mass is 5.974*1024kg Use this data to determine the actual average density of the Earth.

I don't know what it is that I am doing wrong, but I keep getting it wrong, Please solve all the way through, I think I am making a mistake somewhere. Both answers should be kg/m3
