Explanation:
Detailed explanation-1: -The most abundant volcanic rocks are basalt (or basaltic rocks). Basaltic rocks form from very hot molten material and are very enriched in high-temperature mafic minerals.
Detailed explanation-2: -If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. The slow cooling process allows crystals to grow large, giving intrusive igneous rock a coarse-grained or phaneritic texture.
