Inhoud

Aktiwiteit: om metamorfiese gesteentes as ‘n vorm van gesteente te kan bespreek [lu 2.1]

  • Metamorfiese gesteentes is gesteentes wat reeds bestaan het en dan as gevolg van groot druk of hitte verander. Hierdie metamorfose of verandering neem BAIE lank om plaas te vind, aangesien die rots op ‘n sekere diepte onder die aardkors moet wees, waar dit aan uiterste hitte en druk blootgestel kan word. Daarna kan daar maklik 100 miljoen jaar verloop voordat die aardoppervlak so verander is deur erosie dat hierdie gesteentes blootgelê word.
  • Leiklip/Leisteen word gevorm a.g.v. baie groot druk wat op reeds bestaande gesteentes uitgeoefen word.
  • Marmer word gevorm a.g.v. die geweldige hitte waaraan bestaande gesteentes blootgestel word.

OPDRAG 6

  • Verduidelik hoe metamorfiese gesteentes en sedimentêre gesteentes verskil.

Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
