Welcome to the Great Barrier Reef!
The Great Barrier Reef is a huge underwater ecosystem that is made up of reef-building corals, tiny animals called polyps, that are held together by calcium carbonate.
Are coral living animals?
yes no
The Great Barrier Reef is made up of over 3,000 reefs and is home to thousands of species of marine life. The coral reefs are known as the rainforests of the sea because of their incredible biodiversity.
Click on one of the fish that depend on the coral reef for food and shelter.
Welcome to the Great Barrier Reef!
Your challenge is to learn how rising levels of CO2 are affecting the over 2300 km (1400 miles) of coral that make up the Great Barrier Reef.

The pH scale is a measure of the concentration of hydrogen ions. The more hydrogen ions, the lower the pH.
The pH of the ocean deacrease as it absorbs more carbon dioxide (CO2) gas from the atmosphere. Due to chemical reactions that begin with carbon dioxide (CO2) reacting with water (H2O), an increase in carbon dioxide in the ocean leads to a higher concentration of . This is referred to as ocean acidification.
