4.
Pick up the correct statement from the following:
The rise of the ground surface due to frost action is called frost heave.
The freezing of water is accompained by a volume increase of 9%.
Below freezing point, higher soil suction develops.
The magnitude of frost heave decreases as the degree of saturation of soil decreases
All the above.
