How Does Carbon Get Into The Oceans? - The Carbon Cycle

The video explains the significant amount of carbon stored in the ocean, which is about 50 times more than in the atmosphere. It highlights the importance of understanding carbon storage in the deep ocean, where it can remain for long periods. Two main pathways for carbon to reach the deep ocean are discussed: physical processes involving cold dense water and biological processes involving organisms. The video also covers the exchange of carbon dioxide between the ocean and atmosphere, emphasizing the role of plants in this process.

Why is it important to know the amount of carbon in the deep ocean?

• Because it determines the ocean's temperature.

• Because it influences ocean currents.

• Because it can be stored there for long periods, impacting atmospheric carbon levels.

• Because it affects marine life directly.

What is one way carbon is transported into the deep ocean?

• Through evaporation.

• Via cold, dense water sinking in polar regions.

• Through volcanic eruptions.

• By the movement of tectonic plates.

How do marine organisms contribute to carbon storage in the ocean?

• By increasing water temperature.

• By consuming carbon dioxide.

• By forming calcium carbonate structures that eventually become rock.

• By producing oxygen.

What role do plants play in the ocean-atmosphere carbon exchange?

• They increase the ocean's salinity.

• They prevent carbon from entering the ocean.

• They release carbon dioxide into the atmosphere.

• They absorb CO2 and convert it into organic material or shells.

What happens to the CO2 absorbed by plants in the ocean?

• It is used to increase water temperature.

• It evaporates into the air.

• It is converted into carbon or shells and sinks.

• It is released back into the atmosphere immediately.
