Example Questions

Example Question #1 : Atmosphere Ocean Relationships

Which of the following products are NOT exchanged between the ocean and the atmosphere?

Possible Answers:

Heat

Correct answer:

Explanation:

All of the products are exchanged except for nitrogen dioxide; most nitrates are exchanged between the soil and the atmosphere. Oxygen is readily exchanged between air masses and water masses during the water cycle. Carbon dioxide is also absorbed by the oceans from air masses through gas exchange. Lastly, heat is also exchanged mainly due to the differences in specific heat content of water and the surrounding air. 

Example Question #2 : Atmosphere Ocean Relationships

Which of the following does NOT actively remove carbon from the atmosphere?

Possible Answers:

Atmospheric carbon being absorbed by the world's oceans

Fossilization of organic matter

Driving a hybrid car

Planting urban foliage and shelterbelts

Planting/restoring native flora in a disturbed ecosystem

Correct answer:

Driving a hybrid car

Explanation:

Unlike the other processes, driving a hybrid vehicle does not actively remove carbon from the atmosphere. Trees and native flora that are planted absorb atmospheric carbon, fossilization removes carbon from the active recycling of carbon, and carbon dioxide readily dissolves in seawater. Driving a hybrid car releases less carbon into the atmosphere than driving one powered solely by fossil fuels; however, driving a hybrid vehicle does not actively remove carbon from the atmosphere. Hybrid vehicles produce fewer carbon emissions, but they do not take carbon out of the atmosphere.
