Question

Explain the picture in your own words.

Answer 1

Image 'a' represents a crevice or crack which is filled with water wheras image 'b' represents a crevice which has ice. It is evident from both the images that in image 'b', the width of the crevice increases as the water in the crevice freezes. This is one of the properties of water due to which it expands upon freezing. This expansion in water after freezing results in the widening of the crack in image 'b'.
