The Earth's Inner Core The Earth's inner core, whose temperatures go beyond 5,000 degrees, may not present images of a winter wonderland.1 Before you rush to pack your skis, be aware that the "snowflakes (雪花)" are just composed of small pieces of iron!2 The crust is the outermost...
shear energies/ A9135 Earth interiorSOLIDITY of the inner core was originally inferred on the basis of the assumption that the inner core has the same composition as the surrounding material of the outer core 1 . If, however, the observed increase in compressional velocity is related to a ...
compare the process to what happens inside magm a (浆) closer to the Earth's surface.Understanding more about its composition and behavior is very important for scientists to better understand how these larger processes work.1. According to Youjun Zhang, the Earth's inner core is covered ...
Surrounding the inner core of the Earth is Earth's LayersIf you could cut the Earth in half, you could see that it's made of several different layers. The outermost layer, called the crust, is the one that we walk on every day. The layer beneath the crust is called the mantle....
The Earth’s solid inner core is a highly attenuating medium. It consists mainly of iron. The high attenuation of sound wave propagation in the inner core is at odds with the widely accepted paradigm of hexagonal close-packed phase stability under inner
1. Why is an egg mentioned in the second paragraph? A. To explain how the Earth’s core moves. B. To show the importance of the inner core. C. To illustrate the composition of the outer core. D. To help picture the structure of the Earth’s core. 2. What did the scientists disc...

about the inner workings of the Earth by studying the way waves from earthquakes travel through the planet's center. The results suggest that the Earth's inner core may be starting to spin more slowly than the Earth.The Earth's core has two parts: the outer core and the inner core. Bot...
Composition and temperature of the Earth's core constrained by combining ab initio calculations and seismic data It is shown how ab initio techniques based on density functional theory can be used to calculate the chemical potentials of the leading candidate impurity ... D Alfè,MJ Gillan,GD Pri...
Such a mushy zone is also studied in the context of its surrounding ICB regions, which are found to have a sharp boundary. These seismic results suggest that, in the current thermo-compositional state of the Earth’s core, the outer core composition is close to eutectic in most regions ...
