7.11B Humans and Ocean Systems

One of the major ways oceans contribute to weather systems is that the oceans -

• provide a diverse habitat for many organisms.

• store and transport the Sun’s heat energy.

• experience changes in amounts of dissolved salt.

• reach depths that can be as much as 12,000 meters.

How have human activities modified ocean systems?

• Discarded plastics can trap, suffocate, and cause gastrointestinal problems for marine life, resulting in starvation

• Runoff with excessive chemicals can increase nutrients, resulting in more plant growth and reducing the dissolved oxygen content of the water

• Oil from oil spills penetrates the fur and feathers of organisms, causing vulnerability to temperature changes and decreasing buoyancy in water

• All of the answer choices

As the population continues to increase, the pressures on water resources also increase. Which is NOT a reason why an increase in human population correlates with extra pressure on aquatic ecosystems?

• Overfishing

• Decreased salinity in oceans

• Increased numbers of vacations on cruise lines

• Loss of habitat for aquatic animals

Humans depend on ecosystems such as the ocean for survival, yet human activities may alter the ocean system. According to research, all of the following are negative impacts of human activity on the ocean system EXCEPT -

• pollution

• oil rigs

• species invasion

• nutrient-rich water

Which ocean activity is NOT related to survival of humans?

• The oceans store solar energy that helps keep Earth warm

• Marine algae produce a large percentage of the world's oxygen and absorb carbon dioxide

• The oceans play an important role in global weather patterns

• Oceans provide drinking water for most of the world's population
