ES.10 e - Oceans
The student will investigate and understand that oceans are complex, interactive physical, chemical, and biological systems and are subject to long- and short-term variations. Key concepts include
e) economic and public policy issues concerning the oceans and the coastal zone including the Chesapeake Bay.
Bloom's Levels: Analyze; Understand
- The surface of Earth has identifiable major features-- land masses, oceans, rivers, lakes, mountains, canyons, and glaciers.
- Circulation patterns in the oceans are driven by density differences and by exchange of momentum with the atmosphere.
- I can explain why seafood prices go up following a natural disaster.
UNDERSTANDING THE STANDARD
- The oceans are environmentally and economically important. Human activities and public policy have important consequences for the oceans. The impact of human activities, such as waste disposal, construction, and agriculture, affect the water quality within watershed systems and ultimately the ocean. Pollution and overfishing can harm or deplete valuable resources.
- Estuaries, like the Chesapeake Bay, are areas where fresh and salt water mix, producing variations in salinity and high biological activity. Chemical pollution and sedimentation are great threats to the well-being of estuaries and oceans.
In order to meet this standard, it is expected that students will
e) describe how different types of pollution can pollute the Chesapeake Bay even though the pollutant source may be hundreds of miles from the Bay.
