    Why does air temperature change more quickly than water temperature?
    • A. 

      Water has a high specific heat causing it to take much energy for water to change 1º in temperature change. Additionally, air is less dense due to the movement of gas molecules.

      A berm is a ledge or terrace of sand. It is found at the the low tide line extending to the leading edge of the supratidal zone.

  • 20. 
    What is the salinity of the sound/estuary?  Why are sound/estuary waters considered brackish?
    • A. 

      The salinity of an estuary is 15-25 ppt. Sound/estuaries are considered brackish because they are a mixture of fresh and salt water of varied salinities.
