The inner core was discovered in 1936 by Inge Lehmann and is generally believed to be composed primarily of iron and some nickel. Its estimated density is between 12.6 to 13.0 grams to cubic centimeters.

What is the range of density within the outer core?

The density of the outer core ranges from about 9 to 12 grams per cubic centimeter. This variation is due to differences in temperature and pressure within the outer core. The outer core is composed mainly of iron and nickel, which are both dense materials.
