Freezing and thawing of water can cause creep, which is?

- - "Causing creep" Is when a mountain (for example) has a very slow movement of the rocks and sand moving in a downward direction, kind of like an avalanche would have, but in this case, its soil, not snow. 
- - In this case, Freezing can make a solid whilst thawing can make it move, like what a creep is in this question.

What does that mean you dum bum
