Water Resources & Management
📋 What it is
Fresh water is limited and unevenly spread; managing rivers, aquifers and rainfall decides who thrives.
🗣️ Coach says
Almost all Earth’s water is salty or frozen — only a sliver is usable fresh water, and it’s not shared evenly. Whole civilisations rise and fall on who can store, share and clean their water.
🧠 Memory hook
Fresh water is rare and uneven. Store it, share it, keep it clean.

Why are mountains so funny?
Because they're hill-arious!
😲 Whoa!
About 97% of Earth’s water is salty ocean; less than 1% is fresh water we can actually reach and use.
✅ Quick check: Why is fresh water called a "limited resource" when Earth is mostly covered in water?
Say your answer out loud first — then reveal.
Most of Earth’s water is salty ocean or locked in ice; only a tiny fraction is fresh and reachable, and it’s spread unevenly around the world.
Understanding scarcity + uneven supply explains water conflicts and management everywhere.
