Question
What can you tell about an igneous rock that has a fine texture?A.It is most likely extrusive.B.It probably formed underground.C.It is a silicate.D.It formed because of an earthquake.
Solution
An igneous rock with a fine texture is most likely extrusive. This means it probably formed on the surface of the Earth, rather than underground. When molten rock, or magma, erupts onto the surface, it cools quickly, leaving little time for large crystals to form. This results in a fine, or small-grained, texture. Therefore, the correct answer is A. It is most likely extrusive.
