As a fracture is the separation of the geologic formation and that is a joint on the rocks and that divided the rock into small pieces and the rocks. And is commonly caused by the stress and the rocks systems thus is not a chemical weathering process.
<u>Thus the fracture is a fault, a joint and the crack a fault in the axial stretching of the rocks and may also be due to the lithospheric stretching when the band of the rocks moves up and down the horizontal bedding planes.</u>
