WebFreeze-Thaw Weathering or Frost Wedging Frost Wedging occurs when water seeps into cracks of the rocks, freezes and expands, gradually breaking the rock apart into pieces. This expansion leads to the cracking of the rocks from inside and eventually breaks them apart. WebThere are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Freeze-Thaw Most rocks are very hard. However, a very small amount of water can cause them to break. When water seeps into cracks and freezes it then expands. This powerful force can increase the size of cracks.
