yes rough textured rocks do have grains.
Fine textured rocks have a type of grain referred to as aphanitic. This means that its grain is so tiny that it cannot be seen with the naked eye.
Gneissic textured rock.
No. They are usually fine grained.No, lava rocks do not have large grains they have very small grains.
Rocks that are composed of rounded grains or fragments are usually sedimentary rocks. Two of these are sandstone and conglomerate rocks.
Tiny rocks the size of salt grains are generally called, "Sand".
