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.
