Oceans and Climate Change Insights

What is ocean acidification and how does it occur?

• Ocean acidification occurs when the ocean releases carbon dioxide back into the atmosphere.

• Ocean acidification is caused by the depletion of marine life in the ocean.

• Ocean acidification is the process by which the ocean becomes more acidic due to the absorption of carbon dioxide from the atmosphere.

• Ocean acidification is the process of the ocean becoming less acidic due to increased oxygen levels.

How does sea level rise affect coastal communities?

• Sea level rise improves coastal community infrastructure.

• Sea level rise has no effect on coastal communities.

• Sea level rise increases tourism in coastal areas.

• Sea level rise negatively impacts coastal communities by causing flooding, erosion, and displacement.

What are the ecological impacts of overfishing on marine life?

• Overfishing causes depletion of fish populations, disrupts food chains, leads to loss of biodiversity, and results in habitat destruction.

• Overfishing leads to the creation of new habitats for marine life.

• Overfishing increases fish populations and promotes biodiversity.

• Overfishing has no impact on marine ecosystems.

How does plastic pollution affect ocean ecosystems?

• Plastic pollution negatively impacts ocean ecosystems by harming marine life, disrupting food chains, and introducing toxins.

• Plastic pollution has no effect on ocean ecosystems.

• Plastic pollution improves water quality in oceans.

• Plastic waste provides food for marine animals.

What are some effective strategies for climate change mitigation?

• Adopt renewable energy, enhance energy efficiency, promote sustainable transportation, protect forests, and implement carbon pricing.

• Encourage deforestation

• Dismantle public transportation systems

• Increase fossil fuel usage

What role do oceans play in regulating the Earth's climate?

• Oceans primarily serve as a habitat for marine life.

• Oceans have no impact on weather patterns.

• Oceans only affect the temperature of the water surface.

• Oceans regulate the Earth's climate by absorbing solar energy, circulating currents, and acting as carbon sinks.

How does increased carbon dioxide in the atmosphere lead to ocean acidification?

• Increased carbon dioxide creates more oxygen in the ocean.

• Ocean acidification is caused by increased temperatures, not carbon dioxide.

• Increased carbon dioxide in the atmosphere leads to ocean acidification by dissolving in seawater to form carbonic acid, which lowers the ocean's pH.

• Carbon dioxide in the atmosphere has no effect on ocean chemistry.

What are the long-term consequences of rising sea levels on biodiversity?

• Rising sea levels can lead to habitat loss, decreased biodiversity, and disrupted ecosystems.

• Higher sea levels lead to more stable environments for wildlife.

• Rising sea levels have no impact on ecosystems or species.

• Increased sea levels enhance biodiversity by creating new habitats.

How can sustainable fishing practices help combat overfishing?

• Sustainable fishing practices help maintain fish populations and ecosystems, preventing overfishing.

• Sustainable fishing practices have no impact on marine ecosystems.

• Sustainable fishing practices lead to the extinction of certain fish species.

• Sustainable fishing practices increase fish populations by allowing unlimited catches.

What percentage of the Earth's surface do the world's oceans cover?

• 30%

• 50%

• 70%

• 90%
