Q: Which one of the following metamorphic rocks has more weathering resistance characteristics?
  • A. Lime stone
  • B. Phyllite
  • C. Quartzite
  • D. Slate
Correct Answer: Option C - Metamorphic rocks are the igneous or sedimentary rocks, which have been changed due to either pressure or heat or both e.g. quartzite, marble, slate etc. • Quartzite is a hard, non-foliated meta morphic rock which was originally sand stone which is converted into quartzite through heating & pressure. Quartzite has a very good weathering resistance, hardness & crushing strength.
