Question : stones and rocks rising

I’m asking why they rise? I know small stones rise all the time as the rain washes soil down then they eventually rise. I’ve seen areas close to here where enormous rocks 2×2′ can rise up!!! and in my garden areas i’ve dug over last year, i’m finding stones of 4″ that there is no way where there before.

can anyone explain how or why they rise? and how such big ones rise up also.? areas of limestone i know the rocks of quite big sizes are continuously being dug out of the firlds by farmers…

    Have you contacted any local geologists just for shits and giggles? Geology is always in motion (even if it’s slow to us)..There are always geologic pressures pushing and pulling and creating upward forces.

    There could be any number of things happening…pressure pushing rocks up, erosional forces, even freeze/thaw cycles add to it all…There could be something going with underground water tables…

    Geology was always interesting to me but I never got in depth with it except for here where I live. And most of it here was volcanic with the uplifts occurring due to faulting…

    Geology is a wondrous thing..

    “shits and giggles”… i’ve never combined the two thank you very much LOL. In the Jura mountains here the rocks rise and there is still some seismic activity from them. Last was in 2004/5 that gave this area quite a shaking/rumble/lift.

    rofl…shits and giggles is a common saying here..I don’t know why because seriously..if you think about it..it makes no sense whatsoever.

    That’s what I love about geology..it’s in constant motion yet because it’s so slow people take it for granted. It’s a shame more people aren’t interested in it. I took several geology courses in college “just because” and then it came in handy for my actual degree and job. I still couldn’t be a geologist though…I prefer to work with the living and breathing aspect of nature..although one could argue that at certain times geologic forces do seem to take on a life of their own.

    There was actually a college level research project on this question but I can’t find a specific reference, yet.

    The gist is this. Try to visualize a cross section.

    As noted by other posters, the ground is in constant motion. This is due to bending and stretching (gravity), moisture infiltration and drying, creatures (insects, worms, burrowing animals) and many other influences.

    This will create gaps and voids anywhere from microscopic to substantial. If you can visualize what material will tend to fill those voids, large masses of rock, or smaller even fine grained material. Each time this happens a little more material fills the voids which the larger rocks cannot. Over time this filling will raise the larger material bit by bit until it breaks the surface.

    This is all relative. A couple of 2 inch rocks may be raised more easily than a 2 foot boulder. On the other hand the smaller rocks may fill larger voids beneath larger bolders.

    It is simply a process of slow leveraging due to the natural movements of unevenly sized material. You have probably seen this many times as you use a box of cereal or similar product. What is left in the bottom, the larger flakes or flake dust?
