Question

what type of rock has large crystals due to slow cooling?
sedimentary rock
intrusive igneous rock
extrusive igneous rock
metamorphic rock

Explanation:

Intrusive igneous rocks form when magma cools slowly beneath the Earth's surface, allowing large crystals to grow. Sedimentary rocks form from the accumulation of sediments, extrusive igneous rocks cool quickly on the Earth's surface resulting in small crystals or glass - like textures, and metamorphic rocks form from the transformation of existing rocks due to heat and pressure, not from slow - cooling magma for large crystal formation.

Answer:

B. Intrusive igneous rock
