Tectonic plates, plate margins & global patterns
Narrated lesson · press play
Meet the Earth's tectonic plates: what they are made of, how convection in the mantle drags them about, and why the world's fold mountains, earthquakes and volcanoes line up so neatly along their edges — while Namibia sits quietly in the middle.
What you'll learn in this lesson
By the end you should be able to (NSSCAS Geography (AS) 1.1a):
- describe the characteristics of tectonic plates and explain their global patterns
- describe and explain the general distribution of young fold mountains, earthquakes and volcanoes in relation to plate margins: divergent (constructive), conservative and convergent (destructive, collision)
