Lesson: The Water Cycle
The water cycle is a fundamental concept in science that explains how water moves through the Earth's atmosphere. It consists of several key processes that work together to ensure a continuous circulation of water on our planet.

Evaporation
- Evaporation is the process by which water from bodies of water, such as oceans, lakes, and rivers, is heated by the sun and turned into water vapor.
- This water vapor rises into the atmosphere, where it cools and condenses to form clouds.

Condensation
- Condensation occurs when water vapor in the atmosphere cools and transforms back into liquid water, forming clouds.
- These clouds eventually release the water in the form of precipitation, such as rain, snow, or hail.

Precipitation
- Precipitation is the release of water from clouds in the form of rain, snow, sleet, or hail.
- This water returns to the Earth's surface, replenishing bodies of water and contributing to the water cycle.

Runoff
- Runoff is the flow of water over the Earth's surface, which collects in rivers, lakes, and oceans.
- This water eventually evaporates back into the atmosphere, continuing the cycle.

Importance of the Water Cycle
The water cycle is crucial for supporting life on Earth. It ensures a constant supply of fresh water for plants, animals, and humans, regulates the Earth's temperature, and plays a vital role in weather patterns.
Understanding the water cycle is essential for students to grasp the interconnectedness of Earth's systems and the importance of preserving our planet's water resources. By learning about the water cycle, students can develop a greater appreciation for the natural processes that sustain life on Earth.
