FAQs on Learning Poster: Water Cycle - Science for Class 4

1. How does precipitation occur in the water cycle?
Ans. Precipitation occurs in the water cycle when water droplets in the clouds combine and become heavy enough to fall to the ground as rain, snow, sleet, or hail.
2. What is evaporation in the water cycle?
Ans. Evaporation is the process where water from bodies of water like oceans, rivers, and lakes heats up and turns into water vapor, rising into the atmosphere.
3. What role do plants play in the water cycle?
Ans. Plants play a crucial role in the water cycle by absorbing water from the soil through their roots and releasing it back into the atmosphere through a process called transpiration.
4. How does groundwater fit into the water cycle?
Ans. Groundwater is an important component of the water cycle as it is water stored beneath the Earth's surface in soil and rock formations, eventually returning to the surface through springs or being used by plants.
5. How long does the water cycle take to complete?
Ans. The water cycle is a continuous process that can vary in time, but on average, it takes about 1,000 years for a water molecule to complete the entire cycle, from evaporation to precipitation.
