Key Idea: Topic 4.3 is about what sets the pace of global interactions — the human and physical forces that speed them up, slow them down, or actively push back against them. It pulls together two micros: 4.3.1 — what speeds up or slows interactions: the shrinking world and time-space convergence driven by successive transport and communications technology, plus the structures that accelerate flows (MGOs, free-trade zones, EPZs) versus the physical geography and unequal access that slow them. 4.3.2 — resistance to global interactions: the backlash — anti-globalization movements, nationalism and populism, trade restrictions (tariffs, sanctions, resource nationalism), anti-immigration politics and re-shoring — and how effective it actually is. This is HL core content, examined on Paper 3 (HL only): a synoptic two-part essay — a [12] structured part (often Analyse / Examine) plus a [16] markband part (Evaluate / To what extent / Discuss) that rewards named case studies and synoptic links across Units 4-6.
🌍 4.3.1 — What speeds up, and what slows, global interactions
Distant places feel closer because faster transport and communications keep cutting the time and cost of crossing the distance between them — the shrinking world, caused by time-space convergence. The driver is successive technology: sail to steam to rail to jet, and the postal letter to the telegraph, telephone, internet and social media. But technology is not the only control on the pace. Political and economic structures can speed flows up, while physical geography and unequal access slow them down — and the same place can be sped up and slowed down at once.

Tip: For a 'shrinking world' question, work through the eras in order (sail/steam → rail → jet; telegraph → telephone → internet → social media), tying each to a fall in time or cost. Then add the crucial point: the shrinking is uneven — it depends on access, so the digital divide leaves some with a large, slow world.
🚧 4.3.2 — Resistance to global interactions
Globalization is not a one-way street. As trade, migration, media and finance reach deeper into every region, some places and governments push back — they try to slow, block or reverse global interactions. This is resistance, driven by the sense that globalization has costs: lost jobs, cultural change, lost national control. Resistance is uneven and geographical — strongest where the costs are felt most. It can genuinely disrupt and re-route flows, but flows often route around the barriers, and digital flows are very hard to stop.
The top-band judgement on resistance: it is reshaping, not reversing the global economy. It genuinely re-routes trade, re-shores industry and realigns energy — but globalization is too embedded to reverse, so flows adapt and continue. Anchor every form to a named current example and say who drives it.

Exam Tips
- Shrinking world = places feel closer; time-space convergence = the falling time/cost that causes it. The Earth never actually shrinks.
- Run the tech eras in ORDER (sail/steam → rail → jet; telegraph → telephone → internet → social media), each tied to a fall in time or cost.
- Always add the 'uneven' point — perception varies with access; the digital divide matters.
- Speed up = MGOs, free-trade zones, EPZs; slow down = physical geography (relief, distance, isolation) + poor access.
- Resistance = anti-globalization, nationalism/populism, trade restrictions, sanctions, resource nationalism, anti-immigration, re-shoring — anchor every form to a NAMED current example and say WHO drives it.
- Paper 3 = a [12] structured part (Analyse/Examine) + a [16] markband essay (Evaluate/To what extent). The top judgement on resistance: RESHAPING, not REVERSING — and reward synoptic links across Units 4-6.
