The first step in the water cycle is evaporation. This is the process where water from oceans, rivers, and other bodies of water turns into water vapor due to the heat from the sun. This vapor rises into the atmosphere, eventually leading to the formation of clouds and precipitation.

FAQs & Answers

  1. What causes evaporation in the water cycle? Evaporation occurs when the sun's heat warms water in oceans, rivers, and lakes, turning it into water vapor that rises into the atmosphere.
  2. How does evaporation lead to cloud formation? The water vapor from evaporation rises into the atmosphere, cools, and condenses to form clouds.
  3. Why is evaporation important in the water cycle? Evaporation is essential because it initiates the movement of water into the atmosphere, enabling the cycle to continue with condensation and precipitation.
