Fine grained rocks are formed from volcanic eruptions. During these eruptions, the molten magma is cooled fast at or close to the earth surface thereby forming rocks with a fine grained texture. The rock has fine grains because the crystals are small because of the fast cooling of the molten magma. Slow cooling causes the crystals to be large thereby forming coarse rocks such as rocks 2, 3 and 4.
