Options 1st and 5th are the right answer.
Fine-grained textures commonly signify magma that quickly reduced at or near the surface of the earth. Quick cooling limits crystals from developing very big. In simple terms, texture associates to how big the single mineral grains are in the ultimate, dense rock. In most of the cases, the resulting grain dimension depends on how fast the magma chilled. 1 mm is the cutoff separating fine- and coarse-grained composition.
Answer:
1 and 5
Explanation:
As we can see in images 1 and 5, we are not able to see any granule particle, thus these are the fine grain rocks.
When magma cools down slowly, fine grain rocks are formed while when it cools down abruptly then large grain rocks are formed.
Basically the cooling is so fast that it does not provide minute particles with in the magma to move and form any crystal.
Hence, 1 and 5 is the right choice
