Ocean Acidification 2

Front

What is ocean acidification?

Back

Ocean acidification refers to the process by which the pH of seawater decreases due to the absorption of carbon dioxide (CO2) from the atmosphere, leading to harmful effects on marine life.

Front

What causes ocean acidification?

Back

Ocean acidification is primarily caused by carbon dioxide released from combustion of fossil fuels, which is then absorbed by the ocean.

Front

How does ocean acidification affect the pH of seawater?

Back

As the ocean becomes more acidic, the pH of the water decreases.

Front

What is the impact of ocean acidification on marine organisms with calcium carbonate shells?

Back

In a more acidic ocean, the shells of organisms such as corals and mollusks do not grow as easily, making them more vulnerable.

Front

Is human breathing a significant contributor to the rise of CO2 in the atmosphere?

Back

No, because the CO2 was previously removed from the atmosphere through natural processes.

Front

What are carbonate ions and why are they important?

Back

Carbonate ions (CO3^2-) are essential for the formation of calcium carbonate (CaCO3), which is crucial for the growth of shells and skeletons in marine organisms.

Front

What are the potential ecological consequences of ocean acidification?

Back

Potential consequences include disrupted food webs, loss of biodiversity, and weakened marine ecosystems.

Front

How does increased CO2 in the atmosphere lead to ocean acidification?

Back

Increased atmospheric CO2 is absorbed by the ocean, leading to chemical reactions that form carbonic acid, which lowers pH.

Front

What role do phytoplankton play in ocean acidification?

Back

Phytoplankton absorb CO2 during photosynthesis, but increased acidification can affect their growth and survival.

Front

What is the relationship between ocean temperature and acidification?

Back

Warmer ocean temperatures can exacerbate the effects of acidification by reducing the solubility of CO2 in seawater.
