The core–mantle boundary (CMB) of Earth lies between the planet's silicate mantle and its liquid iron-nickel outer core. This boundary is located at approximately 2,891 km (1,796 miles) depth beneath Earth's surface. The boundary is observed via the discontinuity in seismic wave velocities at that depth due to the differences between the acoustic impedances of the solid man… Webb3 nov. 2024 · The outer core is molten rock and it is 2,266 km thick. Finally, the inner core is 1,210 km thick, and it is solid iron and nickel. Remember that as you go deeper into Earth’s layers, temperature and pressure increase. A core sample is made by drilling into the Earth and pulling out a long cylinder of rock.
