Question

figures c & d show two different streams. which stream...

1. is moving down a gentle slope?
2. is moving down a steep slope?
3. is moving faster?
4. is moving slower?
5. carries more sediment?
6. carries less sediment?
7. erodes more?
8. erodes less?

conclusions:

1. water flowing down a steep slope moves (slower/faster) than water flowing down a gentle slope.
2. fast moving water carries (more/less) sediment than slow moving water.
3. fast moving water erodes (more/less) than slow moving water.

Explanation:

Step1: Analyze slope and speed

• Streams on gentle slopes (like Figure C) move slower. Streams on steep slopes (like Figure D) move faster.

Step2: Relate speed and sediment - carrying

• Faster - moving water (Figure D) has more energy to carry more sediment. Slower - moving water (Figure C) carries less.

Step3: Relate speed and erosion

• Faster - moving water (Figure D) erodes more due to its higher energy. Slower - moving water (Figure C) erodes less.

Answer:

1. Figure C
2. Figure D
3. Figure D
4. Figure C
5. Figure D
6. Figure C
7. Figure D
8. Figure C

Conclusions:

1. faster
2. more
3. more
