I WONDER - What Is A Carbon Sink?

The video explains carbon sinks, which are natural systems that absorb carbon from the atmosphere. It highlights two main types: oceans and photosynthesis. Oceans absorb carbon dioxide, forming carbonic acid, which can lead to acid rain if excessive. Photosynthesis, used by plants, converts carbon dioxide, sunlight, and water into energy. Deforestation reduces the capacity for carbon removal, impacting the environment.

What are the two main processes that act as carbon sinks?

• Photosynthesis and respiration

• Ocean absorption and photosynthesis

• Fossil fuel burning and deforestation

• Ocean absorption and volcanic activity

How does the ocean help in reducing atmospheric carbon?

• By storing carbon in marine life

• By releasing carbon into the air

• By forming carbonic acid

• By converting carbon into oxygen

What is a potential negative effect of too much carbonic acid in the ocean?

• Global cooling

• Acid rain

• Increased plant growth

• Decreased oxygen levels

What do plants use during photosynthesis to create energy?

• Carbon dioxide, sunlight, and water

• Oxygen, sunlight, and water

• Sunlight, oxygen, and nitrogen

• Carbon dioxide, oxygen, and water

What is the impact of cutting down trees on carbon removal?

• It increases carbon removal

• It has no effect on carbon levels

• It reduces the amount of carbon that can be removed

• It enhances photosynthesis
