Chapter 28, Problem 1RAT

As a stream moves from a location where gradient is steep to where it is more level, its speed tends to

(a) become turbulent.

(b) meander.

(c) decrease.

(d) increase.

To determine

The correct option for the statement “As a stream moves from a location where gradient is steep to where it is more level, its speed tends to”.

Answer to Problem 1RAT

The correct option for the statement “As a stream moves from a location where gradient is steep to where it is more level, its speed tends to” is option (c).

Explanation of Solution

The gradient of the stream simply means the slope of the hill or place. It describes the steepness of the place. The water moves in a downward direction due to the effect of gravity that pulls the water downward. When the slope of the hill or location is steeper, the speed of flowing water gets increases as compared to the slope, which is less steep. In case, when the stream moves from a steep place to a more level location, the speed of the stream decreases.

Conclusion:

Therefore, the correct option for the statement “As a stream moves from a location where gradient is steep to where it is more level, its speed tends to” is option (c).
