🌧️ Water Cycle Worksheet – Solution & Explanation

#### Part 1: Label the Water Cycle Diagram
You’re given a diagram showing:
- The sun
- Clouds
- Mountains and rivers
- Arrows showing movement of water

Word Bank:
- evaporation
- condensation
- precipitation

Step-by-step labeling:

1. Arrow from water (ocean/lakes) to clouds → Evaporation
- Water turns into vapor due to heat from the sun. This process is evaporation.

2. Arrow from clouds forming → Condensation
- Water vapor cools and forms clouds. This is condensation.

3. Arrow from clouds down to land → Precipitation
- Water falls as rain, snow, sleet, or hail. This is precipitation.

✔ So, label the diagram as follows:
- Evaporation: From water bodies upward toward clouds.
- Condensation: Inside the clouds (or arrow showing vapor turning into clouds).
- Precipitation: From clouds downward to land/water.

#### Part 2: Answer the Questions

##### 1. What causes evaporation?
- ✔ Correct answer: B. sun's energy
- The sun heats water, causing it to turn into vapor. Wind, storms, and animals don’t cause evaporation directly.

##### 2. What is rain that moves into streams, lakes, and rivers called?
- ✔ Correct answer: A. runoff
- Runoff is water that flows over the ground after precipitation and enters rivers, lakes, etc.
- *Snowmelt* is melted snow, not necessarily flowing water.
- *Groundwater* is underground water.
- *Precipitation* is the rain itself, not the movement.

##### 3. Why is it called the water cycle?
- ✔ Answer: Because water continuously moves through different stages—evaporation, condensation, precipitation, and collection—repeating over and over again. It’s a cycle, meaning it repeats endlessly.

🔍 Summary of Key Concepts:

| Term | Definition |
|------|-----------|
| Evaporation | Water changes from liquid to vapor (gas) due to heat (sun). |
| Condensation | Water vapor cools and turns back into liquid, forming clouds. |
| Precipitation | Water falls from clouds as rain, snow, sleet, or hail. |
| Runoff | Water that flows over the surface into rivers, lakes, and oceans. |

✔ Final Answers:

1. Labeling:
- Arrow up from water → Evaporation
- In clouds → Condensation
- Down from clouds → Precipitation

2. What causes evaporation? → B. sun's energy

3. Rain moving into streams/lakes? → A. runoff

4. Why "water cycle"? → Because water constantly moves through the same steps in a repeating pattern.
