The natural process that causes a decrease in the pH of the ocean is called ocean acidification. Ocean acidification is primarily driven by the increased absorption of carbon dioxide (CO2) from the atmosphere into seawater.
When carbon dioxide dissolves in seawater, it undergoes a series of chemical reactions that result in the formation of carbonic acid. This process increases the concentration of hydrogen ions (H+) in the water, leading to a decrease in pH and an increase in acidity. The pH scale ranges from 0 to 14, with lower values indicating higher acidity.
The excess carbon dioxide in the atmosphere, primarily from human activities such as the burning of fossil fuels and deforestation, contributes to the rising levels of carbon dioxide in the oceans. This increased absorption of carbon dioxide alters the chemical balance of seawater, making it more acidic.
Ocean acidification can have significant impacts on marine ecosystems, particularly on organisms that rely on calcium carbonate to build shells or skeletons, such as coral reefs, shellfish, and some species of plankton. The increased acidity makes it more difficult for these organisms to build and maintain their calcium carbonate structures, potentially leading to reduced growth rates, weakened shells, and decreased survival rates.
Addressing ocean acidification requires reducing carbon dioxide emissions and taking steps to mitigate climate change. Understanding and monitoring the impacts of ocean acidification is crucial for the conservation and management of marine ecosystems and the preservation of biodiversity.

The natural process that causes a decrease in the pH of the ocean is known as ocean acidification. This process is caused by the absorption of carbon dioxide from the atmosphere, which increases the acidity of the ocean. This can have serious implications for marine life, as it can affect the ability of organisms to build shells and other structures.
