science 7b changing coral reef quick check
1. What are some possible ways that coral reefs can be impacted by climate change?
- Warmer ocean temperatures can lead to coral bleaching, which weakens the coral and makes it more susceptible to disease and death.
- Ocean acidification can decrease the ability of coral to build their calcium carbonate skeleton, weakening the structure of the reef.
- More frequent and severe storms can physically damage coral reefs and disrupt their environment.
2. How do changes in ocean temperature impact coral reefs?
- Warmer ocean temperatures can lead to coral bleaching, where corals expel the algae living in their tissues, causing them to turn white and weaken. This can ultimately lead to the death of the coral if the stress is prolonged.
3. What is ocean acidification and how does it affect coral reefs?
- Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the absorption of carbon dioxide from the atmosphere. This can make it harder for coral to build their calcium carbonate skeletons, leading to weaker structures and decreased growth.
4. How can human activities contribute to the deterioration of coral reefs?
- Pollution from runoff, overfishing, and physical damage from tourism activities such as snorkeling and diving can all contribute to the deterioration of coral reefs. In addition, the burning of fossil fuels that leads to climate change can also impact coral reefs through ocean warming and acidification.
