Coarsely Crystalline
Describes a rock texture with large, easily visible crystals, typically formed by slow cooling of molten rock.
- Absorb the essentials regarding the mechanisms and environmental conditions impacting the textures of igneous rocks.
- Detail the procedures that magma or lava undergoes to cool and solidify, and the effects these procedures have on the textural properties of the rock.

Final Answer :
D
Explanation :
Coarsely crystalline textures in igneous rocks indicate that the rock cooled slowly, allowing large crystals to form. This typically occurs deep underground, where cooling rates are much slower than at the surface.
