Why metals corode more quickly near the sea?

Metals corrode more quickly near the sea primarily due to the high levels of salt in the ocean, which accelerates the electrochemical reactions that cause corrosion. The presence of moisture in the air also enhances this process, as water serves as an electrolyte that facilitates the flow of electrons. Additionally, sea spray can deposit salt on metal surfaces, further increasing their susceptibility to rust and degradation. Together, these factors create a highly corrosive environment for metals in coastal areas.
