Question

A mining company wants to extract methane hydrates from the seafloor. Which two factors would a marine biologist most likely investigate to determine if this is appropriate?

A. If the area is ecologically sensitive and how the activity would impact the food web

B.The size of the methane deposits and how the activity would impact the water temperature

C. The amount of drilling needed and how the activity would impact the pH of the water

D.The potential energy of the methane deposits and how the activity would impact the deep sea currents

Answer 1

The answer is B. This is due to the fact that methane is a very potent greenhouse gas, 20 times more effective than carbon dioxide in causing global warming. mining of large quantities of the methane hydrates would cause rapid global warming and consequently result in increased ocean temperatures. Increased ocean temperature also contribute to the increased release of methane from the methane hydrates in the oceans hence exacerbating global warming.

Answer 2

The answer is A If the area is ecologically sensitive and how the activity would impact the food web. I just took the quiz and it was correct. Have a good one :)
