Freshwater runoff in rivers from  land is a major source of dissolved salts to the sea.Question 31Select one:TrueFalse

Evaluating the Statement

1. Understanding the Statement: The statement claims that freshwater runoff in rivers from land is a major source of dissolved salts to the sea.

2. Analyzing the Sources of Dissolved Salts:

   • Rivers carry not only freshwater but also dissolved minerals and salts from the soil and rocks they flow over.
   • These dissolved salts include sodium, calcium, potassium, and other minerals that originate from land erosion.

3. Comparing with Other Sources:

   • While rivers contribute to the overall salt content of the ocean, other significant sources include mineral leaching, atmospheric deposition, and direct input from groundwater.
   • However, riverine inputs are indeed one of the key contributors to the ocean's salinity, particularly in coastal regions.

Conclusion

Given that rivers play a critical role in transporting dissolved salts from land to the ocean, the correct answer to the statement is:

Final Answer: True
