the smaller the crystals and the more felsic the composition
the larger the crystals and the more felsic the composition
the larger the crystals and the more mafic the composition

Answer:

he larger the crystals and the more mafic the composition

Step-by-step explanation:

Temperature at which minerals crystallize can determine the nature of composition of the rock and the crystal sizes.

  • When a magma crystallizes at high temperature, the mineral grains have enough time to aggregate around a nuclei.
  • This makes the sizes big.
  • Mafic minerals are know to crystallize at high temperatures.
  • Felsic minerals differentiate at low temperatures.
