This occurs when at night time water may get inside a rock and then freeze the cool climate freezes the water into ice.
it's when water freezes between the joints (vertical line weaknesses on rocks) and melt again, this action creates the spaces between the joints to get bigger and eventually the rock is separated from its original peace. this is freeze thaw.
all types bt only in the coldest area of the world. another word for this is dominant.
Please can someone tell me how long the freeze thaw process takes on a rock, thanks :) xx

The freeze-thaw cycle does happen in Antarctica, but the thaw is never complete.

Freeze.
Answer melt there u have it
Freeze-thaw action is when water seeps into a crack in a rock, as the temperature drops below freezing, the water freezes and expands causing the crack to enlarge. The ice then melts into water again as the temperature rises above 0 degrees C. This action is repeated until the rock breaks.
An example of frost action is when water seeps into cracks in a rock and freezes. As water freezes, it expands and exerts pressure on the rock, causing it to break apart over time. This process is particularly common in cold climates where freeze-thaw cycles occur.

Although in the desert it does drop to the minuses in temperature there is not enough moisture in the air for any freeze thaw.

The freeze thaw is very common up in the high mountains. :)
