Humans and the Hydrosphere

As the population in a region grows, the demand for water also increases. What is a possible consequence for the water resources?

• Water will become more abundant because more people are using it.

• Other species will have to compete more with humans for water.

• Water quality will improve due to higher demand for clean water.

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

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?

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

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

• Marine transportation is affected because dead zones alter shipping routes.

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

Which statement BEST explains how excessive algae blooms impact the stability of the ocean system?

• Excessive algae blooms can deplete oxygen levels in the water through decomposition of the algae, leading to low oxygen levels and negatively impacting marine life.

• Algae blooms have no impact on the stability of the ocean system.

• Excessive algae blooms increase oxygen levels in the water, benefiting marine life.

• Algae blooms lead to a decrease in hydrogen in the water, affecting marine ecosystems.
