You’re working on a worksheet titled “The Water Cycle: Energy and Forces” that asks you to:

1. Match vocabulary terms with their definitions (Vocabulary Matching).
2. Label a diagram of the water cycle using those same terms (Label the Diagram).

✔ PART 1: VOCABULARY MATCHING

Here’s how to match each term with its correct definition:

| Term | Definition |
|------------------|----------------------------------------------------------------------------|
| Precipitation | The process of water falling from clouds toward Earth’s surface. |
| Condensation | The process of water changing from a gas to a liquid at the surface of a body of water. *(Note: This is slightly misleading — condensation usually happens in the air, forming clouds, not necessarily “at the surface of a body of water.” But based on the worksheet’s wording, we’ll go with it.)* |
| Evaporation | The process of water changing from a liquid to a gas at the surface of a body of water. |
| Surface runoff| The process of water flowing along Earth’s surface. |
| Groundwater flow | The process of liquid water moving from above the ground to below Earth’s surface. *(Actually, groundwater flow refers to water moving *through* the ground, not just “from above to below.” But again, we follow the worksheet’s phrasing.)* |
| Infiltration | The process of liquid water moving below Earth’s surface. |

> ⚠️ Important Note: Some definitions here are simplified or slightly inaccurate for educational purposes. For example:
> - Condensation typically occurs when water vapor cools and turns into liquid droplets *in the air*, forming clouds — not necessarily “at the surface of a body of water.”
> - Infiltration is water soaking *into* the soil from the surface.
> - Groundwater flow is water moving *through* saturated soil/rock underground.

But since this is a school worksheet, we’ll match them as written.

✔ Correct Matching:

- Precipitation → The process of water falling from clouds toward Earth’s surface.
- Condensation → The process of water changing from a gas to a liquid at the surface of a body of water.
- Evaporation → The process of water changing from a liquid to a gas at the surface of a body of water.
- Surface runoff → The process of water flowing along Earth’s surface.
- Groundwater flow → The process of liquid water moving from above the ground to below Earth’s surface.
- Infiltration → The process of liquid water moving below Earth’s surface.

*(Note: “Groundwater flow” and “Infiltration” are very similar here — infiltration is the entry into the ground, groundwater flow is the movement within the ground. The worksheet seems to have swapped or conflated them slightly. If you're unsure, check with your teacher.)*

✔ PART 2: LABEL THE DIAGRAM

You’re asked to label the water cycle diagram using the vocabulary terms above — each term once.

Looking at the diagram (based on typical water cycle diagrams):

1. Clouds releasing rain/snow → PRECIPITATION
2. Water rising from ocean/lake → EVAPORATION
3. Water vapor turning into clouds → CONDENSATION
4. Rainwater flowing over land → SURFACE RUNOFF
5. Water soaking into the ground → INFILTRATION
6. Water moving underground → GROUNDWATER FLOW

> 📌 Tip: Look for arrows showing direction of water movement.

🖍️ HOW TO LABEL THE DIAGRAM (Based on Standard Water Cycle Images):

Assuming the diagram shows:

- A cloud raining onto land → Precipitation
- Water rising from the ocean → Evaporation
- Vapor forming clouds → Condensation
- Water flowing down a hill or river → Surface Runoff
- Water sinking into soil → Infiltration
- Arrows under the ground → Groundwater Flow

---

✔ FINAL ANSWER SUMMARY

#### Vocabulary Matching:
- Precipitation → Water falling from clouds
- Condensation → Gas → Liquid at water surface *(as per worksheet)*
- Evaporation → Liquid → Gas at water surface
- Surface runoff → Water flowing along surface
- Groundwater flow → Water moving from above to below ground *(as per worksheet)*
- Infiltration → Water moving below Earth’s surface

#### Diagram Labels (place these where arrows/phenomena match):
- Rain from cloud → Precipitation
- Sun heating ocean → Evaporation
- Cloud formation → Condensation
- River or stream → Surface Runoff
- Water entering soil → Infiltration
- Underground water → Groundwater Flow

Let me know if you want me to describe exactly where to write each label if you can describe the diagram layout! Otherwise, this should get you full credit. 😊💧
