Solution
All of the options provided are correct. Excess sediment in water can cause various problems:
-
It commonly kills fish and aquatic mammals: Sediment can clog fish gills, reducing their resistance to disease, lowering growth rates, and affecting egg and larval development. It can also create a barrier between aquatic mammals and their food sources.
-
It can increase the cost of water purification: Excess sediment can make water treatment more difficult and expensive because it has to be removed before the water can be treated.
-
It can fill in lakes and reservoirs: Over time, sediment can accumulate and reduce the depth of these bodies of water, reducing their capacity to store water.
-
It can obstruct shipping channels: Sediment can build up in shipping channels, making them shallower and more difficult for ships to navigate. This can require costly dredging to remove the sediment.
