Question

Which type of rock has a coarse texture due to slow cooling in magma chambers?

A.extrusive
B.intrusive
C.metamorphic
D.sedimentary

Answer 1

intrusive

Step-by-step explanation:

Intrusive igneous rocks form at some depth within the crust due to slow cooling of magma, resulting in formation of large crystals. Individual crystals can be seen with the naked eye. These rocks are termed texturally as coarsely crystalline or phaneritic.

Answer 2

Answer: Intrusive

Step-by-step explanation:

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.

Hope this helps!! :D
