(computer science) An element that precedes a given element in a data structure. (nuclear physics) A radionuclide that upon disintegration yields a specified nuclide, the daughter, either directly, or indirectly as a later member of a radioactive series. (quantum mechanics) If an n-electron...
(computer science) An additional file sent with an e-mail message. (organic chemistry) The conversion of a molecular entity into another molecular structure solely by formation of a single two-center bond with another molecular entity and no other changes in bonding. ...
An artificial dependence relation between three parents and one child node was determined (causes for anti-gravity of an unknown type of rock) and in a small simulation, participants could choose the influence (strength level of presence or absence) of each cause and observe what happens as an...
Synonyms Mantle rock; Soil parent rock Definition Parent material. The unconsolidated and more or less chemically weathered mineral or organic matter from which the solum of soils is developed by pedogenic processes (Glossary of Soil Science Terms, 1987 ; Resource Conservation Glossary, 1982 ; Soil ...

The study presents X-ray diffraction (XRD), whole-rock geochemistry, and Nd-Sr isotopic data for examining two profiles, 10 and 12 m thick, respectively, that illustrate the regional tropical weathering status in the Midwest of Brazil. The profiles, developed from metasedimentary and sedimentary ...
Soil formation occurs when parent rock material is exposed to the atmosphere or when organic matter, minerals, or both are put on the Earth’s surface [45]. Here, we offer four cases of some of the most significant effects of parent material influences on soil parameters [46]. Providing a...
rock Print Written and fact-checked by The Editors of Encyclopaedia Britannica Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. They write new conten...
time Soils change over time. Clays are secondary minerals. They form in the soil, then change forms, and all the while they are moving downward with leaching rainwater. Similarly, organic matter forms on the surface as it moves downward with rainwater....
But here’s the twist—growing up this way can be like riding a bike with training wheels and then suddenly trying to rock a unicycle on a tightrope.Adults who had all the bells and whistles handed to them tend to freak out more as they get older. Why? Well, imagine getting used to...
