單元大綱

  • Seawater composition in coastal areas is influenced by chemical changes in seafloor sediments. Learn the chemistry of sediments.

    • Observation to collect sediment from the ocean floor

      The collected sediment is cut into layers and the water (pore water) in the sediment is absorbed. Learn why the nutritional content of pore water changes with depth.。


    • Changes in respiratory mode caused by microorganisms

      Respiration is a redox reaction. Learn the forms of respiration by living organisms from the equations of the equilibrium state of redox reactions.
