Ocean Acidification

Front

What is ocean acidification?

Back

Ocean acidification refers to the process by which the ocean becomes more acidic due to the absorption of carbon dioxide (CO2) from the atmosphere.

Front

What greenhouse gas is primarily responsible for ocean acidification?

Back

Carbon dioxide (CO2) is the greenhouse gas primarily responsible for ocean acidification.

Front

How much of the atmospheric CO2 is absorbed by the oceans?

Back

Approximately 1/4 of the atmospheric CO2 is absorbed by the oceans.

Front

What is a major source of man-made CO2 emissions?

Back

The burning of fossil fuels, such as oil, is a major source of man-made CO2 emissions.

Front

What chemical compound is formed when CO2 dissolves in seawater?

Back

When CO2 dissolves in seawater, it forms carbonic acid (H2CO3).

Front

What is the impact of ocean acidification on marine life?

Back

Ocean acidification can harm marine life, particularly organisms that rely on calcium carbonate for their shells and skeletons, such as corals and shellfish.

Front

What is the role of fossil fuels in ocean acidification?

Back

Fossil fuels release CO2 when burned, contributing to increased levels of CO2 in the atmosphere and subsequently in the oceans.

Front

What is carbonic acid?

Back

Carbonic acid is a weak acid formed when carbon dioxide dissolves in water, playing a significant role in ocean chemistry.

Front

How does increased CO2 affect ocean pH levels?

Back

Increased CO2 levels lead to a decrease in ocean pH, making the water more acidic.

Front

What are some effects of ocean acidification on coral reefs?

Back

Ocean acidification can weaken coral reefs, making them more susceptible to damage and reducing their ability to grow.
