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): Region Inner Core Outer Core Mantle Radius (km) Density (kg/m³) 0-1220 13,000 1220-3480 11,100 3480-6371 4,400 Part A Use this model to predict the average density of the entire Earth. Express your answer using four significant figures. IVE ΑΣΦ Pavg 1 = Submit Part B Pavg 2 = Submit Request Answer The measured radius of the Earth is 6371 km and its mass is 5.974 x 1024 kg. Use these data to determine the actual average density of the Earth. Express your answer using four significant figures. Part C IVE ΑΣΦ ? Request Answer kg/m³ ? Compare the actual average density of the Earth Pavg 2 (as a percent difference) with the one you determined in part A. Express your answer using two significant figures.
