Corals don’t live in fresh water.
Who said they did?
My point was simply that this lesson was typical of what our 6 year olds receive as their global climate change primer in schools today.
Wiki has this to say;
“Compositional differences from fresh water
Seawater is more enriched in dissolved ions of all types than fresh water. However, the ratios of various solutes differ dramatically. For instance, although seawater is ~2.8 times more enriched with bicarbonate than river water based on molarity, the percentage of bicarbonate in seawater as a ratio of all dissolved ions is far lower than in river water; bicarbonate ions constitute 48% of river water solutes, but only 0.41% of all seawater ions. Differences like these are due to the varying residence times of seawater solutes; sodium and chlorine have very long residence times, while calcium (vital for carbonate formation) tends to precipitate out much more quickly.”
Not that that enters into your tautology, yet I often wonder if you are after definition or simply attribution.
