Question

Earth's oceans benefit humanity in many ways.

How do the Earth's oceans benefit humans by processing carbon dioxide?
A.
by preventing carbon dioxide from human activities from leaving the air
B.
by absorbing carbon dioxide caused by human activities
C.
by generating carbon dioxide for use in human activities
D.
by providing saltwater for human activities that make carbon dioxide

Answer 1

Answer:

the correct answer is b as oceans transmit and emit carbon dioxide very quickly

Answer 2

Answer:

Earth's oceans benefit humans by processing carbon dioxide

B. by absorbing carbon dioxide caused by human activities.

Explanation:

• The ocean absorbs about 50 times more carbon dioxide than the atmosphere.
• The oceans are very beneficial as they absorb carbon dioxide released by human activities.
• The absorption is done either by diffusion from the atmosphere or by the process of photosynthesis (algae and plankton).
• Around 70% of the earth's surface is covered by the oceans, thus, playing a major role in the absorption of carbon dioxide produced.
• Thus, oceans are important for maintaining the carbon content in the earth's atmosphere.
• Therefore, oceans benefit humans by absorbing the carbon dioxide released due to various activities.
