Water will become a non-renewable resource and run out quickly.

Question 13

In science class, students learn about dead zones in the ocean. Dead zones are areas that form when excess nutrients enter the ocean, leading to oxygen depletion.

Which explanation BEST describes the human industry most impacted by this?

Accepted Answer

Without adequate oxygen commercial fishing is affected because fish cannot survive.

Answer

Tourism is affected because dead zones make coastal waters less attractive.

Answer

Marine transportation is affected because dead zones alter shipping routes.

Answer

Offshore oil drilling is affected because the drilling platform requires oxygen-rich water.

Question 14

Accepted Answer

The rate of extraction must equal the rate of replenishment.

Answer

The rate of extraction must be less than the rate of replenishment.

Answer

The rate of extraction must be greater than the rate of replenishment.

Answer

The rate of extraction must fluctuate less than the rate of replenishment.
