What percentage of the earths mass does the crust make up?
The Earth's crust is approximately 1.65 % of the total volume of Earth.Volume of sphere = 4/3 * pi * r^3Volume of earth = 4/3 * pi * 6,360^3Volume of earth (km3) = 1.078x1012Crust is on average 35 km thick.Therefore radius of earth without crust = 6,360 - 35 = 6,325 km.Volume of earth (not including crust) = 4/3 * pi * 6,325^3 = 1.06x1012 km3Volume of crust = Total volume of earth - Volume of earth (not including crust).Volume of crust = 1.77x1010 km3Percentage of earth's total volume taken by crust = (1.77x1010 / 1.06x1012) * 100Percentage of earth's total volume taken by crust = 1.641 %
