Description

This static image from NOAA's Pacific Marine Environmental Laboratory Carbon Program offers a visually compelling and scientifically sound image of the sea water carbonate chemistry process that leads to ocean acidification and impedes calcification.

Disciplinary Core Ideas

  • In many situations, a dynamic and condition-dependent balance between a reaction and the reverse reaction determines the numbers of all types of molecules present.
  • The many dynamic and delicate feedbacks between the biosphere and other Earth systems cause a continual co-evolution of Earth’s surface and the life that exists on it.
  • Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants.
  • Gradual atmospheric changes were due to plants and other organisms that captured carbon dioxide and released oxygen.
  • Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate.
  • Photoelectric materials emit electrons when they absorb light of a high-enough frequency.
