Question

choose the correct answer. when conducting water tests along a river, where would you expect to find the highest amount of dissolved materials? at the beginning in the middle at the top of the water at the end nearest the ocean

Explanation:

As a river flows, it picks up dissolved materials from the land it passes through. By the time it reaches the end nearest the ocean, it has had the longest distance to accumulate these dissolved materials. At the beginning, there's less time for accumulation. In the middle, it's still in the process. At the top of the water, it's not about the distance of flow which is the main factor for dissolved material accumulation.

Answer:

at the end nearest the ocean
