1. Start at "HERE" and answer the first question: "Most of Earth's surface is covered by...". The correct answer is "water".
2. Move to the next box: "Where is the majority of freshwater stored?". The correct answer is "ice caps, glaciers, etc.".
3. Next question: "Water that flows over Earth's surface and into bodies of water is known as...". The correct answer is "runoff".
4. Next: "In lakes, ponds, rivers + streams...". The correct answer is "surface water".
5. Next: "Where do all rivers and streams eventually drain to?". The correct answer is "ocean".
6. Next: "What separates river basins from each other?". The correct answer is "elevated land (mountainous areas)".
7. Next: "An area of land that remains wet for most or part of the year is known as a...". The correct answer is "wetland".
8. Next: "The process that allows water to become part of groundwater is known as...". The correct answer is "infiltration".
9. Next: "Approximately what percent of water is saltwater (saline)?". The correct answer is "97%".
10. Next: "Approximately what percent of water is stored as groundwater?". The correct answer is "30%".
11. Next: "The amount of water on Earth today is similar to that of millions of years ago because of what process?". The correct answer is "water cycle".
12. Next: "TRUE OR FALSE: Water from an aquifer is likely cleaner than water from surface bodies of water.". The correct answer is "true".
13. Final question: "The Mississippi River Basin is one large river basin made of how many smaller river basins?". The correct answer is "6".
14. End at "END HERE".
The path through the maze is: HERE → water → ice caps, glaciers, etc. → runoff → surface water → ocean → elevated land (mountainous areas) → wetland → infiltration → 97% → 30% → water cycle → true → 6 → END HERE.
