Question

Rocks crack and break into pieces due to the anomalous behaviour of water.
Explain​

Answer 1

Explanation:

Sometimes water enters into crevices of the rocks. When the temperature of the atmosphere falls below 4°C, water expands. Even when water freezes to form ice, there is increase in its volume. As there is no room for expansion, it exerts a tremendous pressure on the rocks which crack and break up into small pieces.
