Nothing stays in *exactly* the same place forever.
If the tree is alive, the nail and the bark around it could be moved outward as the tree forms new rings in its center. If it is high enough on a growing tree, the nail could move farther above the ground.
the tree will heal the damaged area and it will simply grow around the foriegn object.
A nail. A nail always walks on its head when it is driven into a surface.
Nails are not screwed in they are driven in.
A nail is driven flush or below the surface by using a nail punch and a hammer.
becasue the force of the hammer is being doubled, the nail will be droven in twice as far
Gravity helps keep a nail in place
If a nail is not hit square on the top by the hammer it will bend and there is a likelihood that the wood will be damaged by hammer marks or the bent nail.
I dont know
the nail groove provides a surface upon which the nail plate moves as it grows also quiding it straight they also anchor the nail in place
it depends if the nail is put in some place moist surrounded by liquid or just in a dry place
if the nails fall out use nail glue if you don't have nail glue then use a sticking nail polish to keep it in place and not fall out
No, paper is a material used to write on, while nails are used to fasten things together. A better comparison would be nail to hammer, as nails are driven into wood using a hammer.
