Step-by-step solution for: What is the Water Cycle? | Facts for Kids | Twinkl USA
The image you've uploaded illustrates the water cycle, also known as the hydrological cycle. This is a continuous process that describes how water moves through the Earth and its atmosphere. Let's go through each step in the diagram and explain how they contribute to the overall cycle.
---
1. Evaporation
- What happens: The sun heats up water bodies like lakes, rivers, and oceans, causing water to turn into water vapor and rise into the air.
- In the diagram: Arrows show water rising from the surface of the lake and soil into the atmosphere.
2. Transpiration
- What happens: Plants absorb water from the soil through their roots and release water vapor into the air through tiny pores in their leaves (stomata).
- In the diagram: Arrows show water vapor rising from trees and plants.
3. Warm Air Rises
- What happens: As warm, moist air rises, it cools at higher altitudes, leading to condensation.
- In the diagram: The upward arrow from the surface indicates warm air carrying moisture upward.
4. Condensation
- What happens: When warm, moist air rises and cools, water vapor condenses into tiny water droplets, forming clouds.
- In the diagram: Clouds are shown forming above the land and water.
5. Precipitation
- What happens: When the water droplets in clouds become too heavy, they fall back to Earth as rain, snow, sleet, or hail.
- In the diagram: Raindrops falling from clouds onto the land and water.
6. Surface Run-off
- What happens: Some of the precipitation flows over the surface of the land into rivers, lakes, and oceans.
- In the diagram: Arrows show water flowing down slopes into a river.
7. Infiltration
- What happens: Some of the precipitation soaks into the ground, replenishing groundwater stores.
- In the diagram: Arrows show water moving downward into the soil.
8. Groundwater Store
- What happens: Water stored underground in aquifers can slowly move through rock and soil and eventually return to surface water bodies or be used by plants and animals.
- In the diagram: A layer beneath the surface labeled "groundwater store" with arrows showing movement.
9. Return to Evaporation/Transpiration
- The water from groundwater and surface water eventually evaporates again, continuing the cycle.
---
- Energy Source: The sun provides the energy needed for evaporation and transpiration.
- Water Movement: Water continuously cycles between the atmosphere, land, and oceans.
- Human & Ecosystem Impact: Cows and trees in the image suggest that living organisms are part of this cycle (e.g., through transpiration and consumption of water).
---
> Evaporation → Transpiration → Warm air rises → Condensation → Precipitation → Surface run-off & Infiltration → Groundwater store → Back to evaporation
This cycle is essential for life on Earth, providing fresh water for drinking, agriculture, and ecosystems.

🔁 Steps in the Water Cycle (as shown in the image):
1. Evaporation
- What happens: The sun heats up water bodies like lakes, rivers, and oceans, causing water to turn into water vapor and rise into the air.

🌍 Key Concepts Illustrated:
- Energy Source: The sun provides the energy needed for evaporation and transpiration.
- Water Movement: Water continuously cycles between the atmosphere, land, and oceans.
- Human & Ecosystem Impact: Cows and trees in the image suggest that living organisms are part of this cycle (e.g., through transpiration and consumption of water).

✔ Summary of the Water Cycle:
> Evaporation → Transpiration → Warm air rises → Condensation → Precipitation → Surface run-off & Infiltration → Groundwater store → Back to evaporation
This cycle is essential for life on Earth, providing fresh water for drinking, agriculture, and ecosystems.
