Carbon sinks are vital in mitigating climate change by absorbing more CO2 than they emit. Forests, oceans, and soil are key carbon sinks. Forests store carbon through photosynthesis, but deforestation releases it back. Oceans absorb CO2 with the help of phytoplankton, which sequester carbon when they die. Soil stores carbon through decomposition, aided by microbes and fungi. Sustainable practices can enhance these sinks. Protecting these natural processes is crucial for climate stability.

What is the primary function of carbon sinks in relation to climate change?

• To increase greenhouse gas emissions

• To decrease the planet's temperature

• To release carbon dioxide into the atmosphere

• To absorb more carbon dioxide than they release

Which type of forest is particularly efficient at capturing carbon?

• Mangrove forests

• Tropical rainforests

• Boreal forests

• Temperate forests

What happens when forests are damaged or destroyed?

• They release stored carbon back into the atmosphere

• They become more efficient carbon sinks

• They absorb more carbon dioxide

• They increase their capacity to absorb future emissions

What percentage of human-produced carbon dioxide is absorbed by oceans?

• 10%

• 75%

• 25%

• 50%

What role do phytoplankton play in the ocean's carbon sink process?

• They convert carbon dioxide into organic matter

• They decrease marine biodiversity

• They increase ocean acidity

• They release carbon dioxide

Which of the following stores more carbon than the atmosphere and vegetation combined?

• Oceans

• Atmosphere

• Forests

• Soil

How can sustainable agriculture enhance soil's capacity as a carbon sink?

• By stabilizing carbon through decomposition

• By reducing organic matter in the soil

• By decreasing microbial activity

• By increasing soil erosion

What is the ultimate goal of preserving carbon sinks?

• To increase greenhouse gas emissions

• To decrease biodiversity

• To stabilize the climate and ensure a sustainable future

• To increase global warming

Which of the following is NOT a method to enhance carbon sinks?

• Deforestation

• Reforestation

• Conservation

• Sustainable practices

Why is it important to understand and preserve carbon sinks?

• To increase carbon emissions

• To enhance nature's ability to absorb carbon

• To decrease the planet's biodiversity
