  • The term "geosciences" is similarly used to represent only the "solid-earth" sciences or solid and fluid sciences depending on the context, so care must be always exercised when interpreting data regarding the earth science fields from various sources. (nsf.gov)
  • evolution
  • The emergence and expansion of complex eukaryotic life on Earth is linked at a basic level to the secular evolution of surface oxygen levels. (pnas.org)
  • A long-standing and pervasive view is that there have been intimate mechanistic links between the evolution of complex life on Earth-in other words, the emergence and ecological expansion of eukaryotic cells and their aggregation into multicellular organisms-and the secular evolution of ocean−atmosphere oxygen levels ( 1 ). (pnas.org)
  • NASA
  • NASA has funded five new projects to develop tools and technology to make the agency's massive Earth science datasets more accessible and user-friendly. (nasa.gov)

  • I'm not a computer scientist, I'm an Earth scientist," said Lubkin, who now works as a program officer for NASA Earth Science Data Systems' Advancing Collaborative Connections for Earth Systems Science, or ACCESS program. (nasa.gov)
  • Spending large chunks of time simply getting Earth science data into a usable form for analysis is a common situation for researchers working with the big datasets that come from NASA field, airborne and satellite missions. (nasa.gov)
  • We continually invest in development and evaluation of the newest technologies to improve science data systems," said Kevin Murphy, program executive for NASA's Earth Science Data Systems at NASA Headquarters in Washington. (nasa.gov)

  • names
  • four of the rare-earth elements bear names derived from this single location. (wikipedia.org)
  • A table listing the 17 rare-earth elements, their atomic number and symbol, the etymology of their names, and their main usages (see also Applications of lanthanides ) is provided here. (wikipedia.org)
  • form
  • The alkaline earth metals are silver colored, soft metals , which react readily with halogens to form ionic salts , and with water , though not as rapidly as the alkali metals , to form strong alkaline ( basic ) hydroxides . (princeton.edu)
  • All the alkaline earth metals have two electrons in their valence shell, so the energetically preferred state of achieving a filled electron shell is to lose two electrons to form doubly charged positive ions . (princeton.edu)

  • life
  • Earth is currently the only planet known to harbor complex life. (pnas.org)
  • Understanding whether terrestrial biotic complexity is a unique phenomenon or can be expected to be widespread in the universe depends on a mechanistic understanding of the factors that led to the emergence of complex life on Earth. (pnas.org)
  • Further, we argue that a holistic evaluation of environmental variability, organismal life history, and spatial ecological dynamics is essential for a full accounting of the factors that have allowed for the emergence of biological complexity on Earth. (pnas.org)
  • We argue that these effects, when considered in the light of synergistic interactions with other environmental parameters and variable O 2 demand throughout an organism's life history, would have resulted in long-term evolutionary and ecological inhibition of animal life on Earth for much of Middle Proterozoic time (∼1.8-0.8 billion years ago). (pnas.org)
  • Contemporary YEC movements arose in protest to the scientific consensus , established by numerous scientific disciplines, which demonstrates that the age of the universe is around 13.8 billion years, the formation of the Earth happened around 4.5 billion years ago, and the first appearance of life on Earth was at least 3.5 billion years ago.
