  3. Some processes of transfer are rapid while others are very slow.
  4. A conceptual "reservoir" of water is not the same thing as a reservoir in which water is stored.
  5. When land-based glacial ice melts and runs off into the sea, sea level rises.
  6. When land-based glacial ice forms, sea level drops.
  7. When floating icebergs melt into the sea, sea level doesn't change.
  8. Very large icebergs originate from land-based glaciers that break off and fall into the sea, they don't generally form in the ocean.
