1 an andesitic
2 an extrusive
3 a basaltic
4 an intrusive

Answer 1

Answer;

an intrusive igneous rock

Explanation;

-Intrusive, or plutonic, igneous rocks form when magma cools slowly below the Earth's surface. Most intrusive rocks have large, well-formed crystals. Examples include granite, gabbro, diorite and dunite.

-It is formed from magma forced into older rocks at depths within the Earth's crust, which then slowly solidifies below the Earth's surface, though it may later be exposed by erosion, as a result, these rocks are coarse-grained.The mineral grains in such rocks can be identified with the naked eye.
