  1. The water cycle is the continuous process of water movement on, above, and below the Earth's surface, involving phases like evaporation, condensation, precipitation, and runoff.
  2. The water cycle starts with the process of evaporation, where water from oceans, lakes, and other bodies of water turns into water vapor due to the sun's heat.
  3. During condensation, water vapor in the atmosphere cools down and transforms back into liquid water, forming clouds.
  4. Precipitation refers to any form of water, such as rain, snow, sleet, or hail, that falls from clouds and reaches the Earth's surface.
  5. Transpiration is the process by which plants release water vapor into the atmosphere through their leaves, contributing to the water cycle.
  6. Runoff happens when excess water from rain or melting snow flows over the land and doesn't get absorbed, ultimately reaching rivers, lakes, and oceans.
  7. Infiltration occurs when water seeps into the ground and gets absorbed by the soil and rocks, becoming groundwater.
  8. Sublimation is when water changes from a solid (ice or snow) directly into water vapor without becoming liquid first.
  9. Clouds form when water vapor in the air condenses around tiny particles, such as dust or smoke, to create visible water droplets or ice crystals.
  10. Temperature, humidity, and wind speed are factors that can influence the rate of evaporation.
  11. The water cycle influences weather patterns by redistributing moisture in the atmosphere, which affects cloud formation and precipitation.
  12. The water cycle is essential for life as it sustains the availability of fresh water, which is vital for all living organisms.
  13. The sun's energy drives the water cycle by providing heat, which causes evaporation and powers the entire process.
  14. The water cycle affects ecosystems by providing water for plants and animals, influencing climate, and shaping habitats.
  15. Renewable sources of water include rainfall and groundwater, which replenish over time.
  16. Non-renewable sources of water include ancient groundwater trapped in aquifers that cannot be replenished in a human-relevant timescale.
  17. Human activities, such as deforestation, pollution, and excessive water use, can disrupt the water cycle and lead to environmental problems.
  18. Conserving water through practices like fixing leaks, using water-saving appliances, and reducing water waste helps maintain a healthy water cycle.
  19. The different forms of precipitation are rain, snow, sleet, and hail.
  20. The water cycle connects different bodies of water by transporting water through various processes, allowing water to move from oceans to the atmosphere, to the land, and back again.
