Detailed explanation-1: -Ocean acidification is the process in which seawater becomes more acidic because of the excess carbon dioxide (CO2) it is absorbing from the atmosphere.

Detailed explanation-2: -Ocean acidification occurs when carbon dioxide (CO2) is absorbed rapidly into the ocean. It reacts with water molecules (H2O) to form carbonic acid (H2CO3). This compound then breaks down into a hydrogen ion (H+) and bicarbonate (HCO3-). These hydrogen ions decrease seawater pH.

Detailed explanation-3: -Ocean acidification refers to a reduction in the pH of the ocean over an extended period of time, caused primarily by uptake of carbon dioxide (CO2) from the atmosphere.

Detailed explanation-4: -Ocean acidification represents a direct chemical change to global ocean chemistry in response to rising levels of atmospheric carbon dioxide (CO2).

Detailed explanation-5: -Ocean acidification is the ongoing decrease in the pH of the Earth’s ocean. The shell pictured here is a victim of ocean acidification. The normally-protective shell is so thin and fragile, it is transparent. Increased carbon dioxide in the atmosphere is one of the recognized causes of our changing climate.
