Granite has a coarse crystalline texture unless smoothed by weathering and erosion, or by humans.
Its a bit of both but I think it's hard
As cool as sandstone statues may look, it is inevitable that, if exposed to the elements, the statue will slowly be weathered away. The most likely culprits for statue weathering are wind and water, unless of course ice somehow gets involved. Regardless of what does it, the process will likely look the same. The sharpest, most defined features will be weathered away first. Either the wind will slowly eat away at the particles or the water will do the same. Think of a rough surface on a piece of wood. As you rub it continuously with sandpaper, it slowly becomes smooth and less defined. The same works with weathering. Over time, the beautiful statue of Caesar or Napoleon will become a featureless lump of sandstone.
yes rough textured rocks do have grains.

You can try wet sanding the rough areas.
Stones can be either round or rough depending on their weathering, transport and depositional history!
rough board is when the barn that your boarding doesn't do evrything partial rough board would be doing something to take care of your horse, like cleaning, feeding, turning in/out and/or giving water total rough board is doing all of those things
it is if you are sanding down a piece of wood or metal and you need to check that you have everything you need.

Yes you can if you first rough up the ceramic by sanding it. Use a vinyl mastic like Mapei Unibond.

You do not normally need to sand it, unless it's quite rough.
