What is the Forchhammer's principle?

a. The saturation level of seawater
b. The constant proportion of solids in seawater
c. The components of seawater from weathering surface rocks
d. The measure of the total mass of halogen ions


ANS: B
Georg Forchhammer realized that even though oceans may have varying salinity, dissolved solids are
present in the ocean at constant proportions. He also observed that there was less silica and calcium in
the ocean than in river water. These compounds are removed by marine organisms. Information can be
found in the section Understanding the Ocean Began with Voyaging for Trade and Exploration.
