Question

In cold region in winter , the rocks crack due to anomalous expansion of water

Answer 1

In cold region in winter , the rocks crack due to anomalous expansion of water, because of the following reason.

• The anomalous expansion of water is its inability to expand rather than contracting for a temperature change from 4 ° C to 0 °C.
• Even there will be a reduction in the density of water.
• When in solid form the open crystal structure of water is visible.
• Thus, the water present in solid form on the surface of the rock makes the rock cracks.

Answer 2

In cold region in winter , the rocks crack due to anomalous expansion of water

Explanation:

In cold region in winter , the rocks crack due to anomalous expansion of water

Water usually contracts when heated from 0 degrees Celsius  to 4 degrees Celsius  and water expands when cooled from 4 degrees Celsius to 0 degrees Celsius The expansion of water from 4 degrees Celsius to 0 degrees Celsius is called anomalous expansion of water.
