Understanding the Water Cycle

The water cycle represents nature's continuous system of water movement and transformation across Earth's surface and atmosphere. This comprehensive process involves multiple interconnected stages that maintain Earth's water balance.

Definition: The water cycle is the continuous process through which water changes into different states and moves between Earth's surface, atmosphere, and living organisms.

Vocabulary:

• Evaporation: The transformation of liquid water into water vapor through heating
• Condensation: The process where water vapor cools and returns to liquid state
• Precipitation: Water falling from the sky in various forms
• Percolation: The filtering of liquids through porous surfaces
• Transpiration: Water release from plant leaves
• Runoff: Downward water movement due to gravity
• Accumulation: Collection of water in various water bodies

Example: When the sun heats ocean water, it evaporates into water vapor (evaporation). This vapor rises, cools, and forms clouds (condensation), which eventually release water as rain or snow (precipitation).

Highlight: Each stage of the water cycle is essential for maintaining Earth's water distribution and supporting life. The cycle is powered by solar energy and gravity, making it a self-sustaining natural process.
