Is limestone coarse grained or fine grained?
Fine grained rock exhibits a non-visible or nearly non-visible crystalline structure on a fractured surface. On the opposite end, a coarse grained rock exhibits mineral crystals of the rock's constituents on a fractured surface. The larger the crystals, the coarser grained is the rock. Basalt would be an example of a fine grained rock. Granite would be an example of a coarse grained rock.
Which would weather faster a fine grained or a coarse grained igneous rock?

Is metamorphic rock rough or smooth?
Metamorphic rock can be coarse grained or fine grained.
Is fine grained sedimentary rock smooth?
Yes. Fine grained means the grains in the rock are very small. The smaller the grains, the smoother the rock.
