Solution
Weathering is the process of the disintegration or decomposition of rocks at or near the Earth’s surface due to the action of natural agents like water, temperature changes, wind, and biological activity. It leads to the breakdown of rocks into smaller pieces or changes their chemical composition, without any removal of the material from the site.
