atmosphere, and biosphere, as well as their interactions (Fig.1). However, deciphering the evolution of early Earth is challenged by the incomplete preservation of the geological records1. As such, resolving various geoscience conundrums relies on deductive or inductive reasoning (i.e., a ...
The composition and origin of Earth’s earliest continental crust remains enigmatic due to the absence of Hadean (>4 Ga) age rocks. Here we address this question by using machine learning to examine the provenance of the 4.4–3.3 Ga Jack Hills zircons
These are subtle ball-and-socket joints that formed when the area was subjected to horizontal stresses after the rock had cooled and the columns had formed. These ball-and-sockets allow the formation to bend a bit. concave “socket” column top on the left, convex “ball” column top on ...
takes place at an altitude where there is still an appreciable atmosphere, e.g., below about 100,000 feet, the weapon residues almost immediately incorporate material from the surrounding medium and form an intensely hot and luminous mass, roughly spherical in shape, called the “fireball.” An...

The great variety in length of days and nights throughout the year all over Earth testifies to the fact that we do not live on a spinning ball-planet.There cannot exist phenomena such as this on a globe, nor the Midnight Sun, nor anything like Antarctic winter where the Sun is nowhere ...
Rare earth elements (REEs, including the 14 naturally occurring lanthanide elements plus yttrium and scandium) are used in a variety of advanced technology applications such as magnets, catalysts, and other electronic devices. REEs are especially useful for the fabrication of renewable energy technologie...
Structure specific phonon modes are found for the silicide monolayer of (1 × 1) periodicity and for the silicide bilayer of (3−−√×3−−√3×3) periodicity, which, in principle, allow for a structural determination on the basis of the Raman spectra. The good agreement between ...
Earth, Moon, and Sun The Sun The Sun is a burning ball of gas. The Sun gives the Earth HEAT and LIGHT. It provides ENERGY for the Earth. The Sun is the CENTER of our solar system. It DOES NOT MOVE. All the planets REVOLVE around the Sun because of the Sun’s GRAVITY. ...
