Question

As more water flows through a river, its speed will

a. stay the same.
b. increase.
c. decrease.
d. reduce friction between the water and the streambed.

Answer 1

Water flow and speed are directly related. If flow increases, speed must have increased.

The answer is
b) increase

Answer 2

The water in rivers is in constant motion. The speed of the water depends on the slope of the land, the size and shape of the bed, the amount of water, and the amount of material carried by the water. From this follows that as more water flows through a river, its speed will increase. Correct answer: B
