plz help me in my home work experts comment me your ans
Dear student,
Please find below the answer:
Image 'a' shows a crevice (crack) filled with water. In image 'b' the crevice has ice in it. From these images, it is evident that with the freezing of water the breadth of crevice also increases. Water has this property of expanding upon freezing.
The ice in the crack slowly causes widening of rock and eventually this rock breaks. When this ice melts, frost weathering (erosion by carrying away of tiny fragments of rocks) occurs.
Hope this clears your doubt.
Regards.
