  • Previous measurements had shown that in polar springtime, the normally steady levels of mercury in the atmosphere drop to near zero, and scientists studying this atmospheric phenomenon had analyzed a few snow samples and found very high levels of mercury,' says Joel Blum, the John D. MacArthur Professor of Geological Sciences . (umich.edu)
  • atmosphere
  • It was named by the Advisory Committee on Antarctic Names in 1994 named after Ümran Savaş İnan of Stanford University, who has conducted critical research since 1980 in the upper atmosphere of Antarctica at Siple Station and Palmer Station, and is internationally recognized as a leader in the study of upper-atmospheric phenomena.

  • Greenhouse effect is a phenomenon by which carbon dioxide, water vapor, atmospheric methane, nitrous oxide, ozone and aerosol trap more solar heat within the atmosphere causing a global warming. (boloji.com)
  • In his new position, Rafter encouraged research into natural variations in radiocarbon levels, in the process discovering a link between atmospheric nuclear weapons tests and rising levels of radiocarbon in the atmosphere, a phenomenon he and Fergusson called the 'Atom Bomb Effect' when they published their results in 1957. (wikipedia.org)
  • The concentration of oxygen in the atmosphere is often cited as a possible contributor to large-scale evolutionary phenomena, such as the origin of the multicellular Ediacara biota, the Cambrian explosion, trends in animal body size, and other extinction and diversification events. (wikipedia.org)
  • Astrophysics - study of the physical aspects of celestial objects Astronomy - studies the universe beyond Earth, including its formation and development, and the evolution, physics, chemistry, meteorology, and motion of celestial objects (such as galaxies, planets, etc.) and phenomena that originate outside the atmosphere of Earth (such as the cosmic background radiation). (wikipedia.org)
  • carbon cycle
  • Using marine records of the long-term carbon cycle, Torres, West, and Li reconstructed the balance between CO2 release and uptake caused by the uplift of large mountain ranges and found that the release of CO2 release by rock weathering may have played a large, but thus far unrecognized, role in regulating the concentration of atmospheric carbon dioxide over the last roughly 60 million years.

  • Plants
  • Lowered atmospheric CO 2 would also substantially exacerbate plant water stress in marginally arid environments, providing preadapted succulent plants with a sharp advantage in a broader set of ecological conditions and promoting their rapid diversification across the landscape. (pnas.org)
  • solar
  • A time-series analysis of a diverse range of Mesozoic-Cenozoic geological events, particularly extinctions, was independently found to display a similar, dominant ~26- to 30-My periodicity, which was thought to reflect an extraterrestrial forcing, possibly cosmic showers ( 5 ), related to a ~30- to 42-My half-period ( 6 ) of the solar system's oscillation about the plane of the Milky Way galaxy ( 7 ).

  • Geologists view the solar system through earth-coloured spectacles, are volcanoes on Earth, Venus, Mars, Io and Titan the same phenomena? (thunderbolts.info)
  • time
  • Continental rifts were recently identified as one of the main drivers of elevating atmospheric CO 2 during supercontinent fragmentation over long time scales [half-periods of 50 million years (My) and longer] ( 3 ). (sciencemag.org)
  • The geological time span that dates from 359 to 299 million years ago is called the Carboniferous Period. (typepad.com)

  • In geological past when the earth had become a giant deep freeze, the global warming came as a relief for the fauna and the flora to regenerate and rejuvenate. (boloji.com)
  • Left unchecked, however, that process would simply deplete atmospheric CO2 levels to a point that would plunge the Earth into an eternal winter within a few million years during the formation of large mountain ranges like the Himalayas - which has clearly not happened. (wattsupwiththat.com)

  • It is said that the first recorded sighting dates to 1838, in the book Six Months in South Australia, but those are likely to be two different phenomena. (wikipedia.org)
  • In 2012, Sharad Master of the South African Journal of Science has disputed the accuracy of the recording of the event, concluding that the thunderclaps were very likely atmospheric phenomena. (wikipedia.org)

  • Despite the hazard they represent to the immediate surrounding area of the volcano vent, these atmospheric shock waves and the subsequent sonic wave can be safely measured at a long distance from the vent. (mtu.edu)
  • million
  • Like many other large mountain ranges, such as the great Himalayas, the Andes began to form during the Cenozoic period, which began about 60 million years ago and happened to coincide with a major perturbation in the cycling of atmospheric carbon dioxide. (wattsupwiththat.com)
