What's responsible for eutrophication in seawater? A. Deposition of sediments on shorelines B. Groundwater infiltration C. Seafloor spreading D. Runoff of artificial fertilizers
"Deposition of sediments on shorelines" on shorelines is responsible for "eutrophication" in seawater.
Explanation:
The natural process of the addition of nutritional elements to the water is called Eutrophication.
The sediments carried by the rivers and streams flowing into the sea get deposited on the shoreline as these rivers and streams lose the strength to carry these sediments further.
These sediments are rich in nutritional elements like Phosphorous and Nitrogen. The presence of these elements stimulates the growth of algae to a great extent.
