Answer:

slower cooling of magma allows more time for crystals to form intrusive;

Explanation:

  • Coarse-grained igneous rocks are coarse-textured generally indicating the magma that flows slowly and cools deep underground. Hence the minerals tend to crystallize based on the flow patterns of the lava.
  • The column of rocks also goes from felsic to mafic at the bottom. The instinctive rocks are also called plutonic rocks. The slow cooling allows for crystals to grow bigger.
