Interpretation: The photo representing waterline corrosion is given. The reason behind the corrosion of metal pilings most at the waterline and less at the heights above and below the waterline is to be stated.
Concept introduction: The conversion of metal to a form that is more stable, for example conversion of metal to its Oxide, Hydroxide or sulfide is known as corrosion and it basically leads to the destruction of metal either by the normal
To determine: The reason behind the corrosion of metal pilings most at the waterline and less at the heights above and below the waterline.
