Ocean Currents
📋 What it is
Ocean currents are giant rivers within the sea that move warm and cold water — and heat — around the whole planet.
🗣️ Coach says
The ocean is full of invisible rivers. Warm currents carry tropical heat toward the poles; cold currents bring cool water back. That’s why a city can be surprisingly warm or cool for its latitude — the sea next door is doing the work.
🧠 Memory hook
Warm currents warm the coast, cold currents cool it. The sea moves heat.
😂 Giggle
Why did the longitude line feel special?
Because it was one in a meridian!
😲 Whoa!
The Gulf Stream carries so much warm water north that Britain stays milder than Canada — even though they’re at the same latitude.
✅ Quick check: How can two cities at the same latitude have very different climates?
Say your answer out loud first — then reveal.
A warm or cold ocean current flowing past one of them moves heat and changes its climate.
Currents explain climate “surprises” that latitude alone can’t.
