Water Cycle Diagram Worksheet for Learning Key Processes

The image is a worksheet about the Water Cycle. Below, I will fill in the blanks for each term and explain the concepts.

---

1. Precipitation

- Definition: Condensed water vapor that falls back to Earth.
- Examples: Rain, snow, sleet, hail.

Explanation: Precipitation occurs when water droplets or ice crystals in clouds become too heavy and fall to the ground as rain, snow, sleet, or hail.

---

2. Condensation

- Definition: The process of a gas changing into a liquid due to a decrease in temperature or pressure.

Explanation: Condensation happens when water vapor (a gas) cools down and changes into liquid water. This is why dew forms on grass in the morning.

---

3. Sublimation

- Definition: The process of solid and ice changing into gas without first melting into liquid.

Explanation: Sublimation occurs when ice directly turns into water vapor without becoming liquid water. This is common in cold climates where snow or ice can disappear without melting.

---

4. Surface Run-off

- Definition: Water that reaches Earth's surface, flows over land, and reaches lakes, rivers, and oceans.

Explanation: Surface run-off is water that flows over the land after precipitation. It collects in streams, rivers, and eventually oceans.

---

5. Evaporation

- Definition: The process of a liquid changing into a gas due to an increase in temperature or pressure.

Explanation: Evaporation occurs when liquid water turns into water vapor (a gas). This happens when water is heated, such as when the sun warms up a lake or ocean.

---

6. Transpiration

- Definition: Plants absorb water through their roots and then give off water vapor through their leaves.

Explanation: Transpiration is the process by which plants release water vapor into the atmosphere through small openings in their leaves called stomata.

---

7. Infiltration

- Definition: Water soaks into the ground from the ground level and moves into aquifers through soil and pores.

Explanation: Infiltration is the movement of water from the surface into the soil and underground aquifers. This helps replenish groundwater supplies.

---

8. Accumulation

- Definition: Water collects in rivers, lakes, oceans, and other bodies of water as glacial caps and ice caps.

Explanation: Accumulation refers to the collection of water in various forms, such as in rivers, lakes, oceans, glaciers, and ice caps. This is a key part of the water cycle where water is stored before it evaporates again.
