Human Impact on the Earth — Test

Question 18 • Earth and Space Science

Assume that another large oil spill occurred in warm, shallow coastal waters with good oxygen flow. Which outcome would you predict for bioremediation compared to the deep sea?

Answer
A
Recovery would be faster because warm, oxygen-rich conditions support microbial growth.
B
Recovery would fail because nutrients are unnecessary in coastal waters.
C
Recovery would be the same because temperature does not affect microbial activity.
D
Recovery would be slower because shallow water prevents microbial activity.

Explanation

Warm water and plentiful oxygen generally help oil-degrading microbes grow and break down oil more quickly. Compared with the cold, oxygen-limited deep sea, warm, well-oxygenated coastal waters would therefore support faster bioremediation. Choice A, “Recovery would be faster because warm, oxygen-rich conditions support microbial growth,” is correct.
