ES.10 a - Changes in the Ocean

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
a) physical and chemical changes related to tides, waves, currents, sea level and ice cap variations, upwelling, and salinity variations.

Bloom's Levels:  Analyze; Understand

Adopted: 2010

BIG IDEAS

  • Earth's surface is built up and worn down by natural processes, such as rock formation, erosion, and weathering.


  • I can explain what may happen as the Earth's climate changes.

UNDERSTANDING THE STANDARD

  • The ocean is a dynamic system in which many chemical, biological, and physical changes are taking place. The oceans are an important source of food and mineral resources as well as a venue for recreation and transportation. Sea level falls when glacial ice caps grow and rises when the ice caps melt. 

ESSENTIALS

In order to meet this standard, it is expected that students will

a) analyze the role of ocean currents in the distribution of heat from the equatorial regions to the poles, and predict what changes may occur as continents move and atmospheric conditions and climate vary.

KEY VOCABULARY

salinity, wave, crest, trough, wavelength, waveheight, currents, cold water currents, warm water currents, tides, high tide, low tide spring tide, neap tide, continental shelf, continental slope, abyssal plain, mid-ocean ridge, seamount, guyot, trench, estuary
