WebOnce again, this serves as evidence that the earth’s inner core is solid. Answer 3: Seismic waves traveling through the earth refract for the same reason that light refracts when entering different substances (e.g. air, water). The inner core has a different density from the outer core, and this difference in density tells us that it is solid.

WebThe earth is composed of many layers that are classified according to the composition and physical properties. In classifying according to physical properties, there are 5 mechanical layers: lithosphere, aesthenosphere, mesosphere, outer core, and inner core. The outer and inner core are separated by a boundary called the Lehmann discontinuity. WebBy the end of that decade seismic stations were in place all over the world. At the time, geophysicists believed Earth to be made up of a liquid core surrounded by a solid mantle, itself surrounded by a crust, all separated by abrupt density changes in the Earth called “discontinuities.” In 1929 a large earthquake occurred near New Zealand.
