Water on Earth undergoes a continuous cycle, shifting between various states and locations. This process is termed as the water cycle. The stages include:

1.Evaporation: The sun’s rays heat the Earth, causing water from oceans, rivers, lakes, and other sources to evaporate and transform into water vapor.

2.Condensation: As this water vapor rises into the cooler upper atmosphere, it condenses and forms clouds. This is due to the lowering of the temperature, which causes the water vapor to change back into tiny water droplets.

3.Precipitation: When these water droplets in the clouds combine and become heavy, they fall back to the Earth’s surface as precipitation. This can be in the form of rain, snow, sleet, or hail.

4.Collection: After falling to the ground, this water may flow into rivers, lakes, or underground reservoirs. Some of it may be absorbed by plants, while some might evaporate again, repeating the cycle.

The idea that the Earth operates like a terrarium means that the same water recirculates over and over again. The example given about water in Haryana and the Amazon River emphasises the interconnected and cyclical nature of the water system on our planet.
