Aim: Why is the water cycle important to living things?
OBJECTIVE: Explain why the water cycle is important for life on Earth.
Key Term

Lesson Summary
• Life on Earth depends on the cycling of water through the environment.
• The water cycle is the repeated movement of water between Earth’s surface and the atmosphere.
• Earth’s water is recycled through the water cycle.
• Evaporation is the changing of a liquid to a gas.
• Transpiration is the process by which plants lose water through the stomata in their leaves.
