What is the effect of flocculation on deposition in an estuary?
Answer and explanation
Correct answer: Fine clay particles join into larger flocs and settle faster
Flocculation is the aggregation of very fine suspended particles when fresh river water mixes with saline water. Salt ions reduce the repulsive forces between clay particles, allowing them to join into larger, heavier flocs. These settle more readily in the low-energy estuarine environment, increasing mud or silt deposition. Thus option A is correct; the remaining choices describe unrelated glacial, aeolian or karst processes.
