Q: Which is the following is a rock?
  • A. Gypsum
  • B. Augite
  • C. Calcite
  • D. Mica
Correct Answer: Option A - On the basis of geological classification rock is classified as– Gypsum is a chemically precipitated sedimentary types of rock. Augite, calcite and mica are minerals forming rock. 1. Igneous rock–It is also known as primary, unstratified or eruptive rocks one of volcanic origin are formed as a result of solidification of molten mass lying below or above the earth's surface. Example–Granite, basalt, trap etc. 2. Sedimentary rocks–It is also known as aqueous or stratified rocks the various weathering action rain, sun, air, frost etc. breakup the surface of earth and convest sedimentary rock. Example–Gypsum, anhydrite, magnesite, dolomite, limestone etc. 3. Metamorphic rocks–These types formed from igneous or sedimentary rocks as a result of the action the earth movements, temperature changes, liquid pressure etc. Example–Gneiss, marble, schist, slate etc.
