How the Volcanic rocks is different from platonic rocks
  • 1 answers

Gaurav Seth 4 years, 2 months ago

  • Volcanic rocks are fine grained whereas plutonic rocks tend to be coarse grained
  • Volcanic rocks form above the surface while plutonic rocks form beneath the surface.
  • Volcanic rocks form rapidly in geological terms, in a few days at the most, whereas plutonic rocks can take thousands to millions of years to form because it takes much longer for rock beneath the surface to cool down than rock exposed to the atmosphere.
