The water cycle, or hydrologic cycle, involves the continuous movement of water on, above, and below Earth's surface. It consists of key stages such as evaporation, condensation, precipitation, and runoff. Water evaporates from bodies of water, forms clouds through condensation, falls as precipitation, and flows back to bodies of water via runoff, completing the cycle.

FAQs & Answers

  1. What are the main stages of the water cycle? The main stages of the water cycle include evaporation, condensation, precipitation, and runoff, which together enable water to continuously circulate on, above, and below Earth’s surface.
  2. Why is the water cycle important for Earth? The water cycle is essential because it redistributes water throughout the environment, supports life, regulates climate, and helps maintain ecosystems.
  3. What causes water to evaporate during the water cycle? Water evaporates primarily due to heat from the sun, which turns liquid water from bodies like lakes and oceans into water vapor.
