Water changing states
- Water can exist in three different states: solid (ice), liquid (water), and gas (vapor).
- When water gains heat, it can change from solid to liquid (melting) and from liquid to gas (evaporation).
- When water loses heat, it can change from gas to liquid (condensation) and from liquid to solid (freezing).
Water cycle process
- The water cycle involves the continuous movement of water between the Earth's surface and the atmosphere.
- The process includes evaporation of water from bodies of water, condensation of water vapor into clouds, precipitation of rain or snow, and runoff back into bodies of water.
Repeating water cycle
- The water cycle can take place repeatedly because water has the ability to change from one state to another when it gains or loses heat.
- This means that water can evaporate, condense, and precipitate multiple times, allowing the water cycle to continue in a continuous loop.
- This cycle is essential for maintaining a balance of water on Earth and ensuring the availability of water for living things.

Explanation:
The water cycle is the continuous process of water evaporating from the Earth's surface, condensing into clouds, and then returning to the Earth as precipitation. This cycle can take place repeatedly because water has the property of changing from one state to another when it gains or loses heat.
Here is a detailed explanation of why water can change states and why this allows the water cycle to occur repeatedly:
1. Water exists in three states: solid (ice), liquid (water), and gas (water vapor). It can change between these states through the processes of freezing, melting, condensation, and evaporation.
2. When heat is added to water, it gains energy and its temperature increases. At 0°C, water freezes and turns into ice. At 100°C, water boils and turns into water vapor.
3. When heat is removed from water, it loses energy and its temperature decreases. Ice can melt into water, and water vapor can condense into liquid water droplets.
4. These changes in state are crucial to the water cycle. When heat from the sun causes water to evaporate from oceans, lakes, and rivers, it turns into water vapor. This water vapor rises into the atmosphere.
5. As the water vapor rises, it cools down and condenses into tiny water droplets or ice crystals, forming clouds.
6. When the droplets or ice crystals in the clouds become too heavy, they fall back to the Earth's surface as precipitation, including rain, snow, sleet, or hail.
7. The precipitation replenishes water sources such as rivers, lakes, and underground aquifers, and the cycle starts again.
In conclusion, the water cycle can take place repeatedly because water has the ability to change from one state to another when it gains or loses heat. This allows water to evaporate, condense, and precipitate, ensuring a continuous cycle that is vital for the Earth's ecosystems and the survival of living things.
