Understanding Ocean's Role in Carbon Sequestration

How do oceans contribute to the planet's respiratory system?

• By absorbing methane and releasing CO2

• By absorbing CO2 and releasing oxygen

• By absorbing oxygen and releasing CO2

• By absorbing nitrogen and releasing oxygen

What is the main issue with the current level of CO2 emissions?

• They are beneficial for plant growth

• They are overwhelming the oceans' capacity to absorb CO2

• They are causing the oceans to become less acidic

• They are decreasing rapidly

What is 'blue carbon'?

• Carbon stored in industrial facilities

• Carbon stored in marine and coastal ecosystems

• Carbon stored in the atmosphere

• Carbon stored in terrestrial forests

Why is the destruction of coastal ecosystems problematic?

• It increases the amount of carbon they can store

• It releases stored carbon back into the atmosphere

• It has no impact on carbon storage

• It makes them more efficient at absorbing CO2

What is the purpose of a flow reactor in carbon sequestration?

• To increase the acidity of seawater

• To decrease the temperature of seawater

• To convert CO2 in seawater into minerals

• To release more CO2 into the atmosphere

What is a major challenge in implementing carbon management technologies?

• Scientific understanding

• Excessive availability of resources

• Economic and scale challenges

• Lack of interest

What is olivine's role in carbon sequestration?

• It releases CO2 into the atmosphere

• It absorbs CO2 from the atmosphere

• It increases the acidity of the ocean

• It is used to build coastal structures

Why is olivine considered a scalable solution?

• It is rare and difficult to find

• It requires complex chemical processing

• It is only found in specific regions

• It is abundant and simple to use

What is a critical step before implementing carbon removal technologies?

• Increasing CO2 emissions

• Reducing CO2 emissions

• Ignoring CO2 emissions

• Storing CO2 emissions in the atmosphere

What is the main message regarding solutions to carbon emissions?

• A combination of solutions is necessary

• No solutions are currently available

• Only natural solutions should be considered

• There is a single solution that will solve everything
