Answer:
Oceans trap carbon dioxide thereby removing the carbon dioxide from the atmosphere.
Step-by-step explanation:
Carbon dioxide (CO2 ) is one of the trace gases in the atmosphere because it is quite less abundant than oxygen or nitrogen in the atmosphere. However, this trace gas plays an important role in sustaining life of the various species on Earth. It also plays a vital role in controlling the Earth's climate by trapping heat in the atmosphere.
The oceans play a very crucial role in regulating the amount of carbon dioxide in the atmosphere because carbon dioxide can move quickly into and out of the oceans. Once in the oceans, the carbon dioxide no longer traps heat. Hence as a sink for carbon dioxide in nature, oceans benefit humans by absorbing the atmospheric carbon dioxide thereby reducing its concentration in the atmosphere and also reducing its ability to trap heat. Recall that the trapping of heat by carbon dioxide is raising the temperature of the earth. This is known as global warming. We can now say that the trapping of carbon dioxide by oceans may help minimize global warming by maintaining the carbon dioxide balance in nature.
