Answer:
Intrusive rocks have large mineral crystals
Step-by-step explanation:
Most igneous rocks that formed from magma have small mineral crystals but intrusive rocks have comparatively larger crystals. Intrusive igneous rocks cool from magma slowly because they are buried beneath the surface, so they have large crystals. A common example is the granite which is an igneous rock that is composed of four minerals. These minerals are quartz, feldspar, mica, and usually hornblende and its crystals are big in size.
