Igneous rock can be weathered and eroded, and then redeposited and lithified into a sedimentary rock, or be turned into a metamorphic rock due to heat and pressure that change the mineral content of the rock which gives it a characteristic fabric.that involves isolating, describing, and structuring data, usually by typological classification, along with chronological, functional, technological, and constituent determinations.Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state. This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay.Geology can also refer generally to the study of the solid features of any terrestrial planet (such as the geology of the Moon or Mars).Geology gives insight into the history of the Earth by providing the primary evidence for plate tectonics, the evolutionary history of life, and past climates.Computer science and mathematics are used to elaborate the means for transforming simple descriptions of archaeological data into cultural, economic, and social reconstructions of earlier societies.This type of research is attempts to provide archaeology with a theoretical framework based on scientific method.

Free 5-day trial Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.
At the higher end of the energy spectrum, relativistic kinetic energy is the main source of the mass-energy of cosmic rays.
The Oh-My-God particle, the highest-energy fermionic cosmic ray detected to date, had an energy of about times more energetic than the highest-energy detected cosmic photons.
