Slide 3: The Water Cycle

• Evaporation Process: Evaporation occurs when solar energy heats water, transforming it from liquid to vapor. This process accounts for approximately 80% of atmospheric moisture.
• Condensation Formation: As water vapor rises, it cools and condenses into tiny droplets, forming clouds. This process is crucial for weather patterns and accounts for cloud formation.
• Precipitation Types: Precipitation occurs when condensed water droplets combine and fall as rain, snow, or hail. Globally, about 505,000 km³ of water returns to the surface annually.
• Infiltration Importance: Infiltration is the process where water seeps into the ground, replenishing aquifers. It plays a vital role in groundwater recharge and maintaining ecosystem health.
