Lesson 8: Water Quality

Wrapping Up


Reread the article from the The New York Times website. Consider the importance of the elements of the hydrosphere and the relationships between these elements and the oceans.

Things to Review

  • Ecosystems have a natural balance known as a steady state.
  • Disruption in the steady state of an ecosystem does occur with obvious consequences.
  • Elements found in water reservoirs include, but are not limited to, oxygen and nitrogen.
  • The relationship between the components of the hydrosphere and pollution is not positive, yet the pollution does not cause irreparable harm.
