FOLIATION. “The layering within metamorphic rocks is called foliation, and the rock is known as foliated or banded rock. The term "foliation" is derived from the Latin word folia, which means "leaves." https://lnkd.in/eSpeQsqS View in LinkedIn

ROLE OF RAINWATER. “Hot water and other fluids may transport these chemicals rapidly over great distances. Based on the role played by water, metamorphic rocks generally contain many elements that were absent from the original rock, and they lack some that were originally present.” https://lnkd.in/eSpeQsqS View in LinkedIn

ROCKS CONSTANTLY CHANGE. “Metasomatism is the drastic change in the bulk chemical composition of a rock, due to the introduction of chemicals from other surrounding rocks.” https://lnkd.in/eSpeQsqS View in LinkedIn

ADD TEMPERATURE AND PRESSURE. “Many complex reactions may take place, and each resultant mineral assemblage provides us with a clue regarding the temperatures and pressures at the time of metamorphism.” https://lnkd.in/eSpeQsqS View in LinkedIn

METAMORPHIC ROCK. “The process of metamorphism may also involve chemical reactions between minerals, even if they are not in the molten state. In this case, the minerals exchange atoms and new minerals are formed.” https://lnkd.in/eSpeQsqS View in LinkedIn

VAST ION EXCHANGES. “Dilution of the soil solution by the addition of water containing much Ca+2 and Mg+2 favors the leaching of NV1 and the retention of the calcium and magnesium in the exchange sites of clay minerals and organic matter in soils.” https://lnkd.in/ete8CApd View in LinkedIn

LIGHT + MATTER. “In 1905, Albert Einstein (14 March 1879–18 April 1955, Nobel Prize in Physics 1921) published a paper advancing the hypothesis that light energy is carried in discrete quantized packets (photons), each with energy hν to explain experimental data from the photoelectric effect.” https://lnkd.in/eDZvjevE View in LinkedIn

DYNAMIC SOLUTES. “Calcium and magnesium are the dominant exchangeable cations in most soils with a neutral or alkaline reaction. Rainwater dilutes the soil solution, but at the same time it adds appreciable amounts of cations.” https://lnkd.in/ete8CApd View in LinkedIn

QUANTA CONCEPT. “In 1900, while studying black-body radiation, the German physicist Max Planck (23 April 1858–4 October 1947, Nobel Prize in Physics 1918) (Figure 2) suggested that the energy carried by electromagnetic waves could only be released in “packets” of energy.” https://lnkd.in/eDZvjevE View in LinkedIn
