Those That Don't Belive Frost Heaves Enough To Move Coins Around...

....should read this whole Wiki page.

http://en.wikipedia.org/wiki/Frost_heaving

Frost heaving (or a frost heave) results from ice forming beneath the surface of soil during freezing conditions in the atmosphere. The ice grows in the direction of heat loss (vertically toward the surface), starting at the freezing front or boundary in the soil. It requires a water supply to keep feeding the ice crystal growth; and the growing ice is restrained by overlying soil, which applies a load that limits its vertical growth and promotes the formation of a lens-shaped area of ice within the soil. Yet the force of one or more growing ice lenses is sufficient to lift a layer of soil, as much as 30 cm or more.

sure does just look at the rocks that work up out of the ground

I feel that frost does very very very lil at moving coins a round. i feel that goffers, moles and even night crawlers play a bigger part in why coins are on edge and at different angles.

rocks that seem to pop up has more to do with eroision,,, wind and rain

that's my 2 cents, lol

Lol, did you mean golfers or gophers???

I for one know that the bricks in front of my mini-barn doors have been pushed up enough that the doors will not open all the way. I can get in, but they are higher than they normally are. So I believe that this is true. I'm sure other things affect it too, but night crawlers and gophers are deep in the earth right now and haven't caused those bricks to move.

tj, what's going to happen to those bricks when the frost goes out of the ground???? they will go right back down.....

You betcha! I'm counting on it!

They don't always. Sometimes they stay up higher than normal, or they could sink deeper.

Anything that can conceivably push the ground up 30cm is certainly able to reorient objects in it.
