Statement 1: When a soil cover exists, chemical weathering of the underlying rocks is usually stopped.
- This statement is incorrect because soil cover can actually enhance chemical weathering of underlying rocks by providing a medium for water and organic acids to penetrate and react with the rocks.

Statement 2: Pure rainwater acting on bare rock is a strong weathering agent than rainwater acting on the soil.
- This statement is also incorrect because rainwater acting on bare rock may not have any dissolved ions or acids to aid in weathering, while rainwater acting on soil can have organic acids and other dissolved ions that can enhance weathering.

Therefore, the correct answer is option D, none of them.

  • When a soil cover exists, chemical weathering of the underlying rocks does not cease; on the contrary, it is usually enhanced. 
  • This is because the soil absorbs rainwater and keeps the underlying rocks in contact with this moisture. 
  • The rainwater absorbs organic acids from the soil and becomes a stronger weathering agent than pure rainwater acting on bare rock.
