**Earth's Density Model Analysis**The Earth is not a uniform sphere; it consists of regions with varying density. A simplified model of the Earth divides it into three regions—inner core, outer core, and mantle. Each region is assumed to have a unique constant density that reflects the average density of that region in the real Earth:| **Region** | **Radius (km)** | **Density (kg/m³)** ||---------------|-----------------|---------------------|| Inner Core | 0–1220 | 13,000 || Outer Core | 1220–3480 | 11,100 || Mantle | 3480–6380 | 4400 |**Exercises:****(a)** Use this model to predict the average density of the entire Earth.**(b)** Given that the Earth's radius is 6380 km and its mass is \(5.98 \times 10^{24}\) kg, calculate the actual average density of the Earth and compare it (as a percent difference) with the density you determined in part (a).

(a) Use this model to predict the average density of the entire Earth. (b) If the radius of the Earth is 6380 km and its mass is 5.98 x 1024 kg, determine the actual average density of the Earth and compare it (as a percent difference) with the one you determined in (a).
