Questions & Step-by-Step Solutions

What is the average density of the Earth? (2020)
  • Step 1: Understand what density means. Density is how much mass is in a certain volume.
  • Step 2: Know that the average density of the Earth is calculated by taking the total mass of the Earth and dividing it by its total volume.
  • Step 3: The average density of the Earth is approximately 5.5 grams per cubic centimeter (g/cm³).
  • Step 4: Compare this density to the density of the Earth's crust, which is lower than 5.5 g/cm³.
