Minerals of the Earth's Surface ... At the molecular level, clay is a sandwich made of sheets of silica tetrahedra (SiO 4) and sheets of magnesium or aluminum hydroxide (Mg(OH) 2 and Al(OH) 3). Some clays are a proper three-layer sandwich, an Mg/Al layer between two silica layers, while others are open-face sandwiches of two layers.

In terms of consistency, geologists believe the core is largely made up of iron and nickel, as well as lighter elements such as sulfur, oxygen and silicon. New insight into extra-terrestrial life . For Tkalčić, the findings offer a unique chance to “track the evolution of the inner core back in time" and estimate the age of the Earth.

Dr. Inge Lehmann discovered the makeup of the Earth's inner core by studying how an earthquake's waves bounced off the core. It was previously thought that the core was made of liquid, surrounded by solid mantle and a crust. Lehmann found that the Earth's center is made of a solid inner core surrounded by a liquid outer core.

The team’s analyses suggest that geochemical processes deep within Earth—including those involved in our planet’s separation into core, mantle, and crust—sent a large amount of relatively light copper downward to the core-mantle boundary, where it joined immense amounts of sulfur, oxygen, and iron to form a kilometers-thick layer of ...

Researchers have a new explanation for why Earth's inner core remains solid - despite being hotter than the Sun’s Surface. Turns out, it could be due to the atomic architecture of the crystallized iron ball at the center of Earth.

en.wikipedia.org/wiki/Crust_(geology)

The Earth's crust is a thin shell on the outside of the Earth, accounting for less than 1% of Earth's volume. It is the top component of lithosphere: a division of Earth's layers that includes the crust and the upper part of the mantle. The lithosphere is broken into tectonic plates that move, allowing heat to escape from the interior of the Earth into space.

Below it are the outer core and inner core of the Earth, making up about 29% of the Earth's volume, and composed primarily of molten (outer core) or solid (inner core) iron and nickel. The upper mantle (aesthenosphere) has a low density relative to the rest of this layer, and flows fluidly, like a plastic.
