KEY LAG. “Additionally, according to this theory, a sufficiently dim light would be anticipated to show a time lag between the initial shining of its light and the subsequent emission of an electron.” https://lnkd.in/eDZvjevE View in LinkedIn

IONIC GRADIENTS. “In rain deposited farther inland, the ratios Cl"1:Na+1, K+1:Na+1, and SO4"2:CH, expressed as parts per million, differ from those in sea water. A decrease in chloride content of rainwater with distance from the coast has been observed in many countries.” https://lnkd.in/ete8CApd View in LinkedIn

SODIUM CHLORIDE. “The major cations and anions of rainwater come from several sources. Salts are picked up by winds blowing across large stretches of open ocean.” https://lnkd.in/ete8CApd View in LinkedIn

DRIVERS OF FLUX. “Rainwater is a mixed electrolyte that contains varying amounts of major and minor ions. Sodium, potassium, magnesium, calcium, chloride, bicarbonate, and sulfate ions are major constituents, together with ammonia, nitrate, nitrite, nitrogen, and other nitrogenous compounds.” https://lnkd.in/ete8CApd View in LinkedIn

VARIABLE SOLUTES. “Rainwater has a complex chemical composition that varies from place to place, as well as from shower to shower and season to season in the same place. Rainwater contains some constituents of local origin, and some that have been transported by winds from elsewhere.” https://lnkd.in/ete8CApd View in LinkedIn

“WEATHERING rocks, and their redistribution by plants and animals. It is probable that the pH of rainwater, as well as the amount of rain and its contained cations and anions, has an important influence on the weathering of minerals and rocks in any locality.” https://lnkd.in/ete8CApd View in LinkedIn

VAST PH RANGES. “The pH of rainwater in any area varies considerably and seems to form a seasonal and regional pattern. The recorded pH values range from 3.0 to 9.8.” https://lnkd.in/ete8CApd 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
