Answer 1

Steven F answered your question correctly, but so snarkily, I thought I would try to phrase it more nicely. So yes, rocks form as large, often wide-ranging deposits that may be thousands of feet thick and cover hundreds of square miles. Once the rock is exposed to the surface, natural weathering processes work to break it down into smaller pieces. So it is really "How long did the rock take to get so small?" But there is unfortunately no real way to tell. Sorry.

Answer 2

depends on how much water and fertilizer they get?

Of course you might subscribe to the thought that God created that rock so it probably happened in less than one day. Hard to get any more accurate than that.

On the other hand, as was stated before, millions of years of petrogenisis and weathering is probably the best answer. Unless it was an extrusive volcanic rock, then perhaps, depending on your frame of reference, assuming that it's "birth" was on extrusion, perhaps a few minutes as it falls to the ground? Of course the huge rock right next to it may have taken exactly the same time to get that big.

Answer 3

Rocks usually don't grow. They form at whatever size the happen to form at and are eroded over time by wind, water or other elements to which they are exposed. There is no meaningful answer to your question.
