Because not all compounds are soluble or oxidizable in water.

Mohammed Seid Mohammedyasin

Dear Joseph,

This is related to minerals' solubility. Even in the sediment their distribution may depend on hydraulic sorting and grain-size dependent fractionation hence some minerals concentrate on fine grain sediments and the others on coarse grained sediments.

Kind regards

Because the compositions as well as physical state of these two medium are different and also these are different physical and chemical characteristics.
