Geopolitics & Borders

📋 What it is

Borders are agreed lines dividing land into countries; some follow rivers or mountains, others are straight human-drawn lines.

🗣️ Coach says

A border is a decision, not a natural fact. Some follow rivers or mountain ranges; many are ruler-straight lines someone drew on a map. Knowing why a border sits where it does explains a lot of the world’s cooperation — and its conflicts.

🧠 Memory hook

Borders are DECISIONS. Some follow nature, some are drawn straight.
