The core–mantle boundary (CMB in the parlance of solid earth geophysicists) of the Earth lies between the planet's silicate mantle and its liquid iron-nickel outer core. This boundary is located at approximately 2891 km (1796 mi) depth beneath the 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 mantle and the molten outer core.
The internal structure of the Earth is layered in spherical shells: an outer silicate solid crust, a highly viscous asthenosphere and mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
Allow PulseManager::isPulseLoaded to check if pulses from other Mantle mods are loaded, instead of just the same mod. Added static PulseManager::isPulseLoadedGlobal, checks if a pulse is loaded without a PulseManager instance. Can be used by to instantiate without a pulse manager. sections now support attaching a module dependency to pages instead of just sections.
The core is separated from the mantle by Guttenberg’s Discontinuity. It is composed mainly of iron (Fe) and nickel (Ni) and hence it is also called as NIFE. The core constitutes nearly 15% of earth’s volume and 3. % of earth’s mass. The core is the densest layer of the earth with its density ranges between . -14. The Core consists of two sub-layers: the inner core and the outer core. The inner core is in solid state and the outer core is in the liquid state (or semi-liquid). The discontinuity between the upper core and the lower core is called as Lehmann Discontinuity
Earth's mantle is thought to be composed mainly of olivine-rich rock. It has different temperatures at different depths. The temperature is lowest immediately beneath the crust and increases with depth. The highest temperatures occur where the mantle material is in contact with the heat-producing core. This steady increase of temperature with depth is known as the geothermal gradient. The geothermal gradient is responsible for different rock behaviors, and the different rock behaviors are used to divide the mantle into two different zones . However, the inner core is a solid even though its temperature is higher than the outer core. Here, tremendous pressure, produced by the weight of the overlying rocks, is strong enough to crowd the atoms tightly together and prevents the liquid state.
