Question

Even if you live in the middle of North America, the quality of your watershed can affect the quality of the ocean. How can this be? Select one: a. Evaporation carries materials from your watershed to the ocean. Incorrect b. Materials in your watershed are eventually transported to an ocean. c. The amount of water in your watershed will affect ocean evaporation. d. Materials in your watershed are not transported to an ocean.

Answer 1

The appropriate answer is b. Materials in your watershed are eventually trasported to an ocean. A watershed is the land area in which surface runoff enters into a river or river system. All rivers flow from a high elevation (upper course) to a low elevation (lower course). In most cases the lowest point where a river will flow to is the sea. As rivers flow they transport and deposit material along the course and eventually in the sea.
