Tidal Systems & Coastal Ecology
📋 What it is
Where sea meets land, tides create rich zones — tide pools, estuaries — full of specially-adapted life.
🗣️ Coach says
The coast is a dynamic meeting place. Tides expose and cover the shore twice daily, creating TIDE POOLS where creatures survive both wet and dry. ESTUARIES (where rivers meet the sea) mix fresh and salt water into some of the richest nurseries on Earth. Coastal life is tough — adapted to constant change.
🧠 Memory hook
Coasts: tides make tide pools (wet↔dry survivors) + estuaries (fresh meets salt) = rich, tough nurseries.

What did the shrimp say when it hit the reef?
"Oh, crab!"
😲 Whoa!
A tide-pool creature like a barnacle can survive being underwater, then baking in the sun and drying out, twice every single day — extreme adaptation to constant change.
✅ Quick check: Why is life in a tide pool especially tough and specialised?
Say your answer out loud first — then reveal.
It must survive being both underwater and exposed to air/sun as the tide covers and uncovers it twice a day.
Tidal zones demand adaptation to constant change.
