Dissolved silica (SiO2) is supplied to the oceans by the weathering of silicate minerals and its residence time in the oceans is approximately 18,000 years. If the average river
concentration of SiO2 is 10.4 mg/kg and the river flux is about 4.6 x 1016 kg/yr, what is
the steady state concentration of SiO2 (ppm)? (the mass of the ocean is approximately 1.4
x 1021 kg.).
