The Internal Structure of the Earth:The Earth is made up of three main layers namely the crust, mantle, and core. The crust is the outer solid layer. The two inner layers are the mantle and core, respectively.A
A hydrogen atom is traveling high within the outermost layer of Earth's atmosphere. This particular atom first entered the exosphere millions of years ago, but today it overcomes Earth's gravitational pull and escapes, joining the roughly 90 tons of mate
At its core, Earth is a hot rock. Sure, it may not seem that way on a cold, dark morning in the dead of winter, but far below Earth's mostly solid rock surface lies a hot center made almost completely of metal. The earth's liquid outer core is an iron-and-nickel alloy that ser...

But the rotational speed of the inner core is less stable, and has been known to shift over time. Now, researchers are reporting in the journal Nature Geoscience that according to seismic data, the Earth’s inner core may have recently paused its rotation, and could even go on to ...

Earth, if cut in half, would be shown as layers, like a cake. It is made up of four main layers: the crust, the mantle, the outer core, and the inner core. Ingredients in Earth's layers include solid silicate-based rocks and liquid metals....
