Understanding the Water Cycle
Before diving into the quiz questions, it's important to grasp the basic concepts of the water cycle. The cycle consists of several key processes:
- Evaporation: The process where water changes from a liquid to a gas (water vapor) due to heat from the sun.
- Condensation: The process where water vapor cools and changes back into liquid droplets, forming clouds.
- Precipitation: When the droplets in clouds combine and fall back to the Earth as rain, snow, sleet, or hail.
- Collection: Water collects in bodies of water like rivers, lakes, and oceans, where it can once again evaporate.
- Infiltration: Water seeps into the ground, replenishing groundwater supplies.
Understanding these processes will help you tackle the quiz questions effectively.
