Human is an agent of weathering because
- Man is a biological agent of weathering. Due to economic and technological development, man has become the most powerful agent of weathering and erosion.
- Mining, blasting of hills and ridges for road and dam construction, quarrying for industrial and building materials, etc., results in a fast rate of disintegration of rocks.
- This may be accomplished by natural weathering processes in thousands to millions of years.
- Man accelerates the rate of weathering on hill slopes through activities like deforestation.
