✍️ 4. Short Answer Questions
1. What is the primary source of energy that powers the water cycle?
💡 Suggested Answer: The sun is the primary source of energy that powers the water cycle, mainly by causing evaporation.
2. Name two different forms of precipitation.
💡 Suggested Answer: Two forms of precipitation are rain and snow. Other correct answers include sleet and hail.
🎯 5. Multiple Choice
1. Which process describes water vapor turning into tiny liquid droplets to form clouds?
2. Where does most of the Earth's evaporation happen?
3. Which of the following is NOT a stage of the water cycle?
📝 6. Open-Ended Questions
1. Describe what happens during the 'evaporation' stage of the water cycle.
💡 Solution Steps:
During evaporation, the sun's energy heats up liquid water on the Earth's surface, such as in oceans, lakes, rivers, and even puddles. This heat gives the water molecules enough energy to change from a liquid state into an invisible gas called water vapor. This water vapor then rises up into the atmosphere.
2. Explain how a cloud is formed in the sky.
💡 Solution Steps:
A cloud is formed when water vapor, which has risen high into the atmosphere through evaporation, starts to cool down. As the water vapor cools, it changes back into tiny liquid water droplets or ice crystals. These tiny droplets or crystals then gather together around microscopic dust particles in the air, becoming visible to us as clouds.
3. List the four main stages of the water cycle and briefly explain each one.
💡 Solution Steps:
The four main stages of the water cycle are:
1. <strong>Evaporation:</strong> This is when the sun heats up water on Earth's surface, turning it into water vapor that rises into the air.
2. <strong>Condensation:</strong> As water vapor rises higher, it cools and changes back into tiny liquid water droplets or ice crystals, forming clouds.
3. <strong>Precipitation:</strong> When clouds become full of water, the water falls back to Earth in forms like rain, snow, sleet, or hail.
4. <strong>Collection:</strong> After precipitation, water gathers in oceans, lakes, rivers, or soaks into the ground, ready to start the cycle again.
